In order to get anti-UV polyester coating, nano-TiO_2 particles slurry was prepared by ultrasonic-dispersion at first. Then polyester/nano-TiO_2 composite resins and their corresponding polyester/nano-TiO_2 composite films were prepared by in-situ polymerization via slurry above. The composite films were investigated by FT-IR, SEM, SPM, ultraviolet - visible spectroscopy (UV-VIS), respectively. It was found that introduced nano-TiO_2 particles were homodisperse in films and could increase UV absorbanee of the films. The UV shielding ratio of hybrid film can reach 50%-90%.
