摘要

Fluorinated acrylic/silica hybrid latexes have been prepared by mini-emulsion polymerization in the presence of silica nanoparticles functionalized by 3-(methacryloxy) propyltrimethoxysilane. The hybrid particle size and morphology were determined by transmission electron microscopy (TEM). Surface topography of the coating was investigated by atomic force microscopy (AFM) and chemical composition of the surface was analyzed by energy dispersive spectroscopy (EDS). Surface hydrophobicity of the coating was evaluated by water contact angle measurement. The results showed that polymeric latex particles were grafted onto silica. The presence of modified silica in fluorinated acrylic coating favored enrichment of fluorine at the film surface, which contributed to the hydrophobicity of the hybrid film.
