摘要： 以甲基三甲氧基硅烷(MTMS)和 γ-(2，3-环氧丙氧)丙基三甲氧基硅烷(KH560)混合物 为前驱体，通过溶胶凝胶法制备了 MTMS-KH560 复合超疏水涂层，研究了成分配比、溶剂用量、陈化 时间和干燥温度对涂层疏水性能的影响。 利用扫描电子显微镜和傅里叶红外光谱仪对复合超疏水涂 层的形貌和表面化学性质进行了表征。 结果表明:当 V(KH560) ∶V(MTMS) ∶V(CH3OH)= 1 ∶4 ∶50 时， 复合超疏水涂层的接触角达到 153°，并且在 100 ~ 250 °C 热处理温度范围内，涂层的疏水性能几乎保持不变。

Abstract: In this study, we present a simple and efficient method to fabricate a superhydrophobic coating surface on glass substrates by sol-gel method using MTMS and KH560 as coprecursors. we investigated the effects of volume ratio of MTMS/KH560. amount of solvent, aging time and drying temperature on the performance and appearanc of coatings. Field emission scanning electron microscopy(FE-SEM), Fourier transform infrared spectroscopy(FT-IR) and optical contact angle measurements ( CA) were used to characterize the surface morphologies, chemical compositions and wettability of the surfaces, respectively. The results show that when the volume ratio of KH560: MTMS: CH3OH is 1: 4: 50, the coatings have the best performance and the contact angle is about 153 ℃. The property of the superhydrophobic film with micro-nanostructure could be remained when the temperature is between 100~250 ℃.
