Abstract

Environmental issues, such as global warming, have been increasing, due to the rapid consumption of petrol-based resources. Therefore green composites based on natural fibers and biodegradable polymers have rapidly developed and have found wide applications as building and transport materials because of their high specific strength and eco-friendliness. However, compared with traditional materials like metal and ceramics, these plant fiber-based biocomposites are less thermally stable and much more flammable, due to their chemical structure features. Thus it is extremely necessary to enhance the thermal stability and flame retardancy to ensure their safe applications. This chapter focuses on discussing types of natural fibers, biopolymers, and currently available flame retardants, the thermal properties and flammability of natural fiber-based biocomposites and possible flame retardancy mechanisms. Although great advances have been made with regards to enhancing thermal stability and flame retardancy of these biocomposites, there are still some challenges to be addressed.

Fire behaviour of waterborne intumescent coatings on timber substrate for bushfire exposure
2023, Fire Safety Journal
The fire behaviour of radiata pine timber, treated with intumescent coatings and exposed to heat flux conditions equivalent to a high-risk bushfire attack level (BAL) is investigated. The experiment is designed for coated timber exposed to bushfire attack levels greater than 19 kW/m² and up to 29 kW/m² (BAL-29) in accordance with AS 3959. The timber was coated with a DFT of 400 μm of the developed intumescent formulations based on expandable graphite (EG), ammonium polyphosphate (APP) and a waterborne acrylic resin with high adhesion strength. The coated timbers were tested according to AS3959, for a BAL-29 rating, using a cone calorimeter at 25 kW/m² for 10 min. Most of the coated samples reported a substantial reduction in the peak heat release rate (p-HRR) and average HRR with values not greater than 100 kW/m² and 60 kW/m², respectively. These results satisfy the requirements for bushfire-resistant timber at BAL-29 rating. Formulation 4 (F4), with EG:APP ratio of 3:1 and resin content of 45 wt% was identified as the most cost-effective formulation. Coatings with high loading of EG and APP provided the best fire protection to the timber substrate, however, a larger char with a less compact structure is formed.
Synthesis and characterization of an intumescent halloysite based fire-retardant epoxy system
2023, Applied Clay Science
In this research, a halloysite-based nitrogen-phosphorous fire retardant epoxy system was evaluated. The synthesized melamine phosphate in combination with pentaerythritol as an intumescent fire retardant which was effective in previous studies was introduced. To achieve a strong and thermally stable char residue a tubular high aspect ratio halloysite nanotube to make bridgeable network and reducing flame spread as a promising reinforcing nanoclay was proposed. The present study focuses on investigating the fire retardant capabilities of partially cured melamine formaldehyde resin that has been used to cover fire retardant additives. The synthesized fire retardant additives were characterized by spectroscopic, microscopic analysis, etc. The synthesized fire retardant additives had an excellent effect on fire retardancy of epoxy resin and the strength of residual char. Thermogravimetric analysis data showed that suitable amount of halloysite had positive effect on the char residue to protect the substrate at high temperatures. Cone calorimetery test showed that the epoxy based fire retardant sample was successful to release heat slowly, and slow down the burning process by the formation of an efficient char on the surface of the substrate. The total smoke released by epoxy based fire retardant sample was 1469.1 m²/m² while that of neat epoxy was 5589.6 m²/m².
Development and characterization of rigid packaging material using cellulose/sugarcane bagasse and natural resins
2023, International Journal of Biological Macromolecules
Composites developed from cellulose and natural resins have received much attention due to their low cost and positive environmental impact. Knowledge of the mechanical and degradation characteristics of cellulose based composite boards is essential to obtain indications of the strength and degradability of the resulting rigid packaging material. The composite was prepared with sugarcane bagasse and hybrid resin (a combination of epoxy and natural resin such as dammar, pine, and cashew nut shell liquid) with the mixing ratios (Bagasse fibers: Epoxy resin: Natural resin) 1:1:1.5, 1:1:1.75, and 1:1:2 using compression moulding method. Tensile strength, young's modulus, flexural strength, soil burial weight loss, microbial degradation, and CO₂ evolution was determined. Cashew nut shell liquid (CNSL) resin-incorporated composite boards in the mixing ratio of 1:1:2 gave maximum flexural strength (5.10 MPa), tensile strength (3.10 MPa), and tensile modulus (0.97 MPa). The maximum degradation in soil burial test and CO₂ evolution between the boards made using natural resin was found in the composite boards incorporated with CNSL resin with a mixing ratio of 1:1:1.5 were 8.30 % and 12.8 % respectively. The maximum weight loss percentage (3.49) in microbial degradation analysis was found in the composite board made using dammar resin in the mixing ratio of 1:1:1.5.
A review of sustainable and environment-friendly flame retardants used in plastics

Intumescent FR's have a carbon-based substance, dehydrating, and foam-forming agents. They are environmentally friendly as they release less smoke and have low toxicity [21,22]. Although all the aforementioned FR's are efficient in improving the fire performance of plastics, there have been concerns about toxicity under fire conditions in relation to environmental issues encountered as a result of leaching of FRs, incineration, and recycling problems.
The progressive transition from conventional structural designs to lightweight and more complex structures has led to the increase in the quantity of plastic materials in buildings. However, plastics have a major flaw: their low fire performance characterised by shorter ignition times and higher heat release rates. This has necessitated the incorporation of flame retardants (FRs) in plastics. Nevertheless, not all FRs are environmentally safe, hence, there is an urgent need for the development of sustainable biobased FRs that reduce environmental footprints while simultaneously improving the fire performance of plastics. This article addresses the negative connotation of FRs and reviews the most extensively used biobased FRs in plastics, their preparation (synthesis) and mode of application, performance evaluation as well as the leaching of FRs, and environmental fate. Some interesting observations in the review are the reduction of ignition times of plastics by the addition of FRs due to the rapid volatilisation of samples. In addition, the leaching rate of FRs is found to be higher in finer particles (micro and nanoparticles) compared to larger-sized ones and has the potential to dissolve in humic matter hence endangering the lives of humans and animals.

It is so effective to hinder the volatile gases and heat transfer over the forced combustion test. Meanwhile, the Intumescent Fire Retardant (IFR) was applied in this report as the most promising environmentally-friendly flame retardant and on account of the fairly low toxicity and smoke and high proficiency [104]. Numberless studies have stated that applying IFRs along with additives as reactants can be considered as an effective procedure to enhance fire retardancy with a good mechanical property and lower loading [105].
Epoxy resins are the most prominent thermoset material, which has been extensively applied in a diversity of industries including aerospace, coatings, electronics, and biomedical systems. Due to the shortcomings of epoxy, the desire to use nanocomposites has been increased and become a hot research topic. The GO and MOF-filled composites, due to their fantastic mechanical, thermal, and barrier characteristics, have provided crucial insights for decades. Additionally, although the inherent defects of GO and MOF particles have vastly bounded their constructive applications, presently, the GO-modified MOF particles have been prospered. The mixture of the porous MOFs and GO nanosheets reinforces the physicochemical properties that enable them to be used in a wide range of fundamental technologies. We will entirely summarize the recent advances of MOFs decorated GO nanohybrids in the epoxy resin, and their effects on the constructed composite coating's mechanical & thermal, anti-corrosion, and flame-diminishing properties. Reports evidenced that the introduction of GO and MOF-based nanohybrids into Epoxy resin has provided central insights for decades because of their outstanding mechanical, thermal, and barrier characteristics. The plus and minus of GO and MOF nanofillers can be avoided and boosted by modification of GO via MOFs, respectively. A high reduction of peak heat release rate (p-HRR) up to 41% and the total smoke production decrement up to 30% were reported by the addition of GO-MOF nanohybrids to the EP in comparing with GO-EP nanocomposite, proving the improvement of the flame-retardant properties of epoxy resin. Through screening the literature it is obvious that through the introduction of GO/Ln-MOF nanoparticles into Epoxy resin the anti-corrosion stability of the epoxy resin was greatly improved and reached the 500% level. The adhesion strengths were enhanced up to 100%. In addition, the storage modulus ratio improvement percentile would be about 20% and the energy at the breakpoint was improved by 275%.

On the other hand, red phosphorous is odourless and is not absorbed into the systemic circulation causing no potential toxicity [2]. It is used in producing the safety matches, semiconductors, smoke bombs, fertilizers and pesticides, lithium-ion batteries [3], photocatalyst [4], and as a flame retardant [5]. Black Phosphorous has recently witnessed several breakthroughs in the fundamental research and biomedical applications due to its biocompatibility and physicochemical properties.
Black Phosphorous has recently gained the attention in the field of 2D nanomaterials owing to its exceptional structure and properties. Specifically, its features like drug loading efficiency, biocompatibility, optical, mechanical, electrical, thermal and phototherapeutic properties contribute to its rising demand as potential alternative to the graphene-based 2D nanomaterials in biomedical applications. Though the BP’s outlook appears promising, its practical applicability is highly challenging. In this review we have discussed the different strategies for synthesis of BP and then briefed its unique properties which renders it a potential platform for the biomedical application. We then discuss the importance of heterogeneous doping on improving the stability of BP against chemical degradation and enhancing its photoelectric properties. Meanwhile, BP-based nanoconjugates, stimuli responsive nanoplatforms, therapeutic, imaging and biosensing platforms are the domains of special and comprehensive interest for versatile biomedical applications of BP. The physicochemical interactions at the nano-bio interface like protein corona formation on the surface on nanoparticles due to interaction with the plasma proteins and others play a crucial role in the biological effects of BP. Hence, we have also discussed the recent studies on interactions between Black phosphorus based nanoconstructs with various biological molecules. Further, it is vital to consider the fact that, though biocompatible, BP-nanomaterials can induce inflammatory responses and exhibit toxicity in dose and time dependant manner. Therefore, we have briefed the biodegradation and toxicological aspects of BP to enlighten the readers about the safety and toxicity of black phosphorous. The future developments of this 2D nanomaterial will not only serve as a boon for oncology, but also functions as a potential nanoplatform for other biomedical applications.
