采用溶胶-凝胶法在含氟硅聚丙烯酸酯(FSiPA)乳液中，以正硅酸乙酯(TEOS)为前驱体，甲基三乙氧基硅烷(MTES)为改性剂合成疏水性二氧化硅(SiO2)纳米粒子，将所制杂化乳液喷涂在玻璃表面得到超疏水涂层。考察了FSiPA乳液用量和MTES/TEOS物质的量比(M/T)对涂层表面性能的影响；分析了M/T值对涂层微观形貌的影响；讨论了杂化涂层的形成机理；比较了具有相同倾角的超疏水涂层与普通疏水涂层表面的自清洁特性。结果表明：，当FSiPA乳液用量为15%，M/T为5时，涂层表面具有很好的成膜性和自清洁特性，疏水性SiO2纳米粒子能够在涂层表面建立起微/纳米粗糙结构，涂层与水的静态接触角(WCA)为154.0°。

First, with tetraethoxysilane (TEOS) as precursor and methyltriethoxysilane (MTES) as modifier, hydrophobic silica nano-particles were synthesized in polyacrylate emulsion containing siloxane and fluorine (FSiPA) by means of the sol-gel method. Next, superhydrophobic coatings were fabricated by spraying the SiO2/FSiPA hybrid emulsion on clean glass substrates. Then, the authors analyzed the effects of the FSiPA emulsion dosage and the mole ratio of MTES to TEOS (M/T) on the coating performance were analyzed and explored the effect of M/T on the coating micro-morphology was explored. Finally, the formation mechanism of the hybrid coating was discussed, and the self-cleaning properties of the superhydrophobic and hydrophobic coating tilting at the same angle were also compared. The results show that, when the FSiPA emulsion content iswas 15% and the M/T iswas 5, the coating possesses good film-forming property and self-cleaning property with a water contact angle of about 154.0°, and the hydrophobic silica particles can form rough micro/nanostructure on the coating surface.
