采用静电纺丝技术在玻璃基片表面构筑聚乙烯醇( PVA)纳米纤维网膜,以正硅酸丁酯( TEOS)为硅源,通过气相沉积法向 PVA 纳米纤维网膜间隙中引入 SiO2纳米粒子.然后以六甲基二硅氮烷( HMDS)为修饰剂,对玻璃基片表面 PVA /SiO2膜进行疏水改性,从而降低其表面能.利用扫描电镜(SEM),静态水接触角(WCA)等测试手段对在玻璃表面制备的 PVA /SiO2/HMDS 薄膜进行了表征.结果显示,处理过的玻璃基片具有较高的粗糙度,表面水接触角( WCA)达135.7°,表明其具有很好的疏水性能.而且制备的薄膜疏水性能稳定,耐磨性能好,能够保持较好的透明性.因此在高档室外墙体、汽车挡风玻璃、眼镜片等领域具有潜在的应用前景.

@@@@Here, the poly -vinyl -alcohol(PVA) nanofibers omentum are prepared on the surface of the glass substrate via electrospinning, then terabutyl orthosilicate is used as a precursor to induce silica particles to the omentum , and lastly bis(trime-thylsilyl)amine is coated on PVA /SiO2 omentum for reducing the surface energy.The prepared PVA /SiO2 /HMDS film on glass substrate is characterized by SEM images, water contact angle (WCA) and so on.The results show that the surface of the treated glass possesses higher roughness, WCA of the thin film reaches 135.7°, indicating the prepared film has good hydrophobic per-formance.Also the film presents excellent transparency and wear -stability, which may be widely applied in high -grade outdoor wall body, windscreen and spectacle lens, etc.
