Preparation of SiO₂/Cenoshpere Composites and Super-Hydrophobic Surface

Abstract:

Nano SiO₂/ cenoshpere composites were prepared to obtain the core-shell structure by chemical precipitation and heterogeneous nucleation. This kind of composites can be further used to fabricate super-hydrophobic surface. In this study, industrial fly ash cenoshpere and water glass solution were used as raw materials. The aim was to coat a layer of Nano SiO₂ on the surface of cenosphere. By tests of SEM, XRD, FTIR, XPS, the mechanism of coating process was discussed. Treat the composites with KH-570, and then use this kind of particles to prepare super-hydrophobic surface.
