以正硅酸乙酯(TEOS)、γ-缩水甘油醚氧丙基三甲氧基硅烷(GPTMS)、甲基三乙氧基硅烷(MTES)和十七氟癸基三甲氧基硅烷(FAS)为前驱体,通过溶胶凝胶法分别独立制备3种特性不同的溶胶。然后,通过逐次浸涂,依次构筑涂层的基底层、结构层和修饰层。最后,经过一次热处理工艺制备出复合超疏水涂层。采用扫描电镜,原子力显微镜对涂层的表观形貌进行表征,紫外-可见光谱和水接触角测量仪表征涂层的可见光透过率和疏水性能,同时测试了涂层的硬度,附着力等机械性能。结果表明,涂层对水接触角可达155°,可见光透过率高于70%。
(TEOS), γ-glycidoxypropyltrimethoxysilane (GPTMS), methyltriethoxysilane (MTES) and heptadecafluorodecyltrimethoxysilane (FAS) Precursor, separately prepared by sol-gel method three different characteristics of the sol. Then, by successive dip-coating, the underlying layers of the coating, the structural layer, and the modifying layer are sequentially constructed. Finally, after a heat treatment process to prepare a composite super-hydrophobic coating. The morphology of the coating was characterized by scanning electron microscopy and atomic force microscopy. The visible light transmittance and hydrophobicity of the coatings were characterized by UV-Vis spectroscopy and water contact angle meter. The hardness and adhesion of the coatings were also tested Mechanical behavior. The results show that the coating has a water contact angle of 155 ° and a visible light transmittance of more than 70%.
