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(trimethylsilyl)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 rough...
