基于溶胶凝胶法的超疏水纺织物的制备及其性能
Preparation and Properties of Superhydrophobic Textiles Based on Sol-Gel Method
摘要
Abstract
Superhydrophobic materials have become one of the research hotspots in coating directions in recent years because of their special wetting properties.Due to their anti-icing,self-cleaning,drag reduction and other characteristics,it has a wide range of application prospects.In this paper,SA-SiO2/PPSsuperhydrophobic coatings with a thickness of about 38 µm were prepared on the surface of textile cloth using nano silica(SiO2),stearic acid(SA)and polyphenylene sulfide(PPS)as raw materials by sol-gel method.The morphology was analyzed by electron scanning microscope,and the properties of the sample coating were tested.The microcosmic properties of the coating were analyzed by molecular dynamics simulation.The results show that the water contact angle of 56%SA-SiO2/30%PPS coating is 154.8°,which shows good self-cleaning,corrosion resistance and soaping resistance.Scanning electron microscopy(SEM)analysis shows that the material has micro and nano-scale rough structure.The surface of SiO2 and SA molecules was connected by hydrogen bond.The molecular dynamics simulation was consistent with the experimental data,and the corrosion resistance of the coating was verified from the microscopic point of view.关键词
