摘　　要：采用喷涂法,将硅藻土和纳米氧化铝经十六烷基三甲氧基硅烷修饰后,加入树脂液配制成喷涂液涂覆在多种基底表面,经固化后,可获得表面水静态接触角高达163.4°的超疏水表面。该涂层具有优异的拒水、耐腐蚀、减阻、油水分离、表面自清洁性及抗覆冰性能。在防水自清洁纺织品、金属表面的防腐、流体机械的减阻及电力网络的防覆冰领域均有一定的应用前景。The surface of diatomite and alumina particles was modified by hexadecyltrimethoxysilane(HDTMOS),and then the suspensions were sprayed on different substrate surfaces according to certain proportion.After curing,the superhydrophobic surface with the static water droplets contact angle of 163.4°can was obtained.The coating had excellent water repellent,corrosion resistance,drag reduction,oil-water separation,surface self-cleaning and ice resistance.It had a certain application prospect in the fields of waterproof and self-cleaning textiles,anticorrosion of metal surface,drag reduction of fluid machinery and anti-icing of power network.
