Abstract

Titania nanoparticles (nano-TiO2) core and fluoropolymer shell TiO2/fluorocopolymer composites were successfully prepared by emulsion polymerization. Before synthesis, nano-TiO2 was modified by coupling agent 3-(trimethoxysilyl) propyl methacrylate (MPS) in advance. The chemical groups and composition of the nanocomposite were characterized by Fourier transform infrared (FTIR) and 1H NMR, respectively. In addition, transmission electron microscopy (TEM) was used to confirm the core-shell structure. Finally, the influence of TiO2 content on the properties of the nanocomposite was investigated using thermogravimetric analysis (TGA), contact angle goniometer, and atomic force microscopy (AFM). The results showed that compared with the properties of pure polymer, the addition of nano-TiO2 can improved the thermostability and led to the higher hydrophilic properties.
