摘    要:采用溶胶-凝胶法,以正硅酸乙酯(TEOS)和甲基三乙氧基硅烷(MTES)为前驱体、硅丙树脂为成膜物质,制备了有机-无机杂化超疏水材料.在对用该材料获得超疏水涂层的研究中,考察了硅丙树脂的含量,比值n(MTES)/n(TEOS)、n(C_2H_5OH)/n(TEOS)和n(NH_3·H_2O)/n(TEOS)对涂层性能的影响.测试结果表明,当硅丙树脂加入量占总物料量的25%(质量分数),摩尔比n(TEOS)∶n(MTES)∶n(C_2H_5OH)∶n(NH_3·H_2O)为1∶4∶30∶10时,涂层具有良好的疏水性和均匀的外观结构,涂层静态水接触角可达156°.

关 键 词:超疏水涂层  溶胶-凝胶法  有机-无机杂化  水接触角

Abstract:An organic-inorganic hybrid superhydrophobic coating was prepared by sol-gel method with tetraethoxysilane(TEOS)and methyltriethoxysilane(MTES)as precursors and silicone acrylate resin as film-forming materials.The effects of the content of silicone acrylate resin and the molar ratios of MTES to TEOS,C_2H_5OH to TEOS and NH_3·H_2O to TEOS on coating performance were studied.The test results showed that the hybrid coating has good hydrophobicity and uniform appearance.The static state water contact angle is up to 156° when the content of silicone acrylate resin is 25%(mass fraction)and the molar ratio of TEOS:MTES:C_2H_2OH∶NH_3·H_2O is 1∶4∶30∶10.
Keywords:superhydrophobic coating  sol-gel method  organic-inorganic hybrid  water contact angle
