A novel photodegradable thin film of poly(vinyl chloride) (PVC) composite was prepared by embedding modified TiO 2 nanoparticles into the commercial PVC. The photocatalyst nanoparticles were modified with perchlorinated iron (II) phthalocyanine (FePcCl 16 ) to improve their photocatalytic activity. Solid‐phase photocatalytic degradation of the PVC‐FePcCl 16 ‐TiO 2 thin film was carried out under ultraviolet (UV) lamp or sunlight irradiation in atmosphere. The properties of composite films were compared with those of pure PVC film and poly(vinyl chloride)‐TiO 2 (PVC‐TiO 2 ) composite films through performing weight loss monitoring, scanning electron microscope and Fourier‐transform infrared spectroscopy. The results indicated that the degradation efficiency of PVC‐FePcCl 16 ‐TiO 2 composite film was significantly higher than that of pure PVC film and PVC‐TiO 2 composite film under UV or sunlight irradiation. The photocatalytic degradation mechanism was discussed briefly. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
