超疏水聚硅氧烷涂层的制备及其性能OA北大核心CSCDCSTPCD
Preparation and Properties of Superhydrophobic Polysiloxane Coatings
采用溶胶-凝胶法,以甲基三乙氧基硅烷(MTES)为有机硅前驱体,通过酸-碱催化水解-缩合得到聚有机硅氧烷凝胶,经浸涂-提拉成膜技术在玻璃表面制备超疏水聚硅氧烷涂层.通过红外光谱(FT-IR)、水接触角(WCA)和场发射扫描电子显微镜(FE-SEM)等分析技术对涂层进行了结构表征、疏水性测试和表面形貌观察.结果表明,涂层内部形成带有甲基和残余硅羟基基团的网络结构.当n(MTES)∶n(EtOH)∶n( H2O)分别为1∶35∶8和1∶45∶8时,在…查看全部>>
Using methyltriethoxysilane(MTES) as precursor, the polysiloxane gels were obtained by a sol-gel approach based on the acid-base catalysis mechanisms. Subsequently, the superhydrophobic polysiloxane coatings were fabricated on a glass at room temperature by a simple dip coating technique. The chemical composition, hydrophobicity and morphology of the resultant coatings were investigated by Fourier transform infrared spectrum (FT-IR) , water contact angle…查看全部>>
