Preparation of Fluorinated Diol/Poly(vinyl alcohol)/Silica/Zirconium Composites Possessing an Oleophobic/Superhydrophilic Characteristic:Application to the SurfaceModification

摘要

Fluorinated aliphatic alcohols [RF-CH2CH2OH;RF = CF3(CF2)n;n = 3,5,7] were applied tothe preparation of the corresponding fluorinated alcohols/silica nanocomposites[RF-CH2-CH2OH/SiO2] through the sol-gel reactions of the corresponding alcohols withtetraethoxysilane (TEOS) and silica nanoparticles under alkaline conditions to exhibit asuperhydrophilic characteristic with a superoleophobicity on the modified surface.Fromthe practical point of view,it is of particular interest to develop the modified glass surfacepossessing not only an oleophobic/superhydrophilic characteristic but also a good adhesionability toward the glass surface by using the fluorinated aliphatic alcohols/silicananocomposites.
