The synthesis and study of silica thin films’ adhesive properties as a function of dimethyldimethoxysilane: tetraethoxysilane (DMDMS: TEOS (DT)) molar ratio and calcination temperature and its relationship with the silica polymer shape have been conducted. DT molar ratio was very influential on the silica thin film’s hydrophobic nature coated on the glass surface and indicated that the water droplets stuck to the silica-coated glass surface, not rolling down. The sticky property mainly originated from the non-uniformity of functional group composition and material surface roughness. The highest hydrophobic properties were obtained from the balanced composition of the DT molar ratio.

进行了二氧化硅薄膜的粘合性能随二甲基二甲氧基硅烷：四乙氧基硅烷（DMDMS：TEOS（DT））摩尔比和煅烧温度及其与二氧化硅聚合物形状的关系的合成和研究。DT摩尔比对涂覆在玻璃表面上的二氧化硅薄膜的疏水性有很大的影响，表明水滴粘附在涂覆二氧化硅的玻璃表面上而不滚动。粘性主要源自官能团组成和材料表面粗糙度的不均匀性。从DT摩尔比的平衡组成获得最高的疏水性。
