Fabrication of Super-Hydrophobic Textile Surface with Aminopolysiloxane and Nano-Silica via a Solution Immersion Process

Article Preview

Abstract:

In this article, we exploited a solution immersion method to conveniently construct a superhydrophobic textile surface with N-β-aminoethyl-γ-aminopropyl polysiloxane (ASO-1) and nano-silica and then investigated its micro-morphology and ultra-hydrophobic property using Field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS) and Static water contact angle analyzer, respectively. Results show that a hydrophobic film and many lotus-leaf-like micro-nano scale tubercles are coated on the textile surface, which are the reasons why the textile changed from hydrophilicity to super-hydrophobicity. Optimal ASO-1 dosage and processing time are 0.25 wt% ASO-1 in toluene solution and 15 minutes. In addition, with increase of the experimental nano-silica diameters at 30-280.7 nm, super-hydrophobicity of the treated textile surface slightly increases.
