摘　　要：采用十六烷基三乙氧基硅烷(HDTES)和纳米二氧化硅(SiO_(2))为原料,通过水解缩聚,合成出一种改性纳米硅溶胶(SiO_(2)@HDTES),并将其与实验室自制的氨基硅树脂(ASi)复合,制备出一种新型有机-无机纳米杂化复合材料(ASi/SiO_(2)@HDTES)。以ASi/SiO_(2)@HDTES为成膜物质,采用喷涂技术在织物表面上得到无氟超疏水织物涂层。利用红外光谱(FT-IR)、热分析仪(TGA)、X射线光电子能谱仪(XPS)、接触角测量仪(OCA)、原子力显微镜(AFM)等对产物结构和性能进行测试和表征。结果表明:涂层表面具有微纳米级的分层结构,水接触角为152.8°,滚动角为8.4°,涂层可在室温下固化并具有良好的自清洁性能。该超疏水织物涂层具有无氟、无污染、环保等特点。A modified nano-silica sol(SiO_(2)@HDTES)is synthesized by hydrolytic condensation using cetyltriethoxysilane(HDTES)and nano-silica(SiO_(2))as raw materials,and a new organic-inorganic nano-hybrid composite(ASi/SiO_(2)@HDTES)is prepared by compounding it with a self-made aminosilicone resin(ASi)in the laboratory.With ASi/SiO_(2)@HDTES as the film-forming substance,a fluorine-free superhydrophobic fabric coating is obtained by spraying technique.The structure and properties of the products are tested and characterized by infrared spectroscopy(FT-IR),thermal analyzer(TGA),X-ray photoelectron spectroscopy(XPS),contact angle measurement(OCA),and atomic force microscopy(AFM).The results show that the surface of the coating has a micro-and nano-level layered structure,the water contact angle of the fabric coating is 152.8°,the rolling angle is 8.4°,and the coating can be cured at room temperature and has good self-cleaning performance.The superhydrophobic fabric coating is fluorine-free,pollution-free and environmentally friendly.
