Paper Abstract

Interaction between polymers and nanoparticles are known to influence structure and properties of polymer materials containing dispersed nanomaterials. Titanium oxide was prepared by sol-gel method and used as inorganic materials; polyvinyl alcohol was used as polymer matrix. The objectives of this paper are to synthesize and characterized TiO2 - polymer composite. TiO2 nanoparticles were dispersed in polymer solution with the aid of ultrasonic vibration to obtained polymer composite materials. The properties of TiO2 - polymer composite films were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and optical microscopy. FT-IR showed that there existed a strong interaction at the interface of TiO2 and polymer, which implied that the polymer chains were grafted onto the surface of TiO2 nanoparticles. It can be also be seen from SEM images that the TiO2 nanoparticles were perfect dispersed in polymer matrix.
