成功制备了乙烯基修饰的二氧化硅纳米粒子（V-SiOx-NPs）超疏水膜。V-SiOx-NPs的表面粗糙，主要是由V-SiOx-NPs表面的纳米结构和V-SiOx-NPs表面的微结构组成，而不是由V-SiOx-NPs表面的超疏水性组成。然后研究V-SiOx-NP的接触角与直径之间的关系。具有150- 1600 nm V-SiOx-NP的膜的固着接触角（CA）为约166，而与直径无关，而具有85 nm V-SiOx-NP的膜具有约158的最低CA。V-SiOx-NP的填充方式决定了表面上的空气分数，然后是CA。(C)2008 Elsevier B. V.保留所有权利。
Super-hydrophobic films with vinyl-modified silica nanoparticles (V-SiOx-NPs) were successfully prepared. The rough surface, which was composed of microstructures of disordered V-SiOx-NPs and nanostructures on the surface of V-SiOx-NPs, rather than the chemical composition devoted to the super-hydrophobicity of film. The relationship between contact angle and diameter of V-SiOx-NPs was then investigated. The sessile contact angles (CA) of films with 150-1600nm V-SiOx-NPs were around 166 regardless the diameter, while the film with 85 nm V-SiOx-NPs had the lowest CA of about 158. The packing manner of V-SiOx-NPs determined the air fraction on the surface and then the CA. (C) 2008 Elsevier B.V. All rights reserved.
