UV-Durable Superhydrophobic Textiles with UV-Shielding Property by Coating Fibers with ZnO/SiO2 Core/Shell Particles

Article Preview

Abstract:

ZnO/SiO2 core/shell particles were fabricated and coated on poly (ethylene terephthalate) (PET) textiles, followed by hydrophobization with hexadecyltrimethoxysilane, to achieve superdrophobic surfaces with UV-shielding property. Transmission electron microscopy (TEM) was employed to reveal the fabrication of ZnO/SiO2 core/shell particles. Scanning electron microscopy (SEM) was conducted to investigate the surface morphologies of the textile and the coating of the fibers. UV-Vis spectrophotometry and contact angle measurement indicated that the incorporation of ZnO onto fibers imparted UV-blocking property to the textile surface, while the coating of SiO2 shell on ZnO made the superhydrophobicity of the as-treated PET textile surface UV-durable.
