Abstract: In this research, photodegradable polyvinyl chloride (PVC) – poly(ethylene oxide) (PEO) – titanium dioxide (TiO2) composite film was prepared by mixing PEO with TiO2 nano-photocatalyst in to the PVC matrix. The photocatalytic degradation behavior of PVC – PEO – TiO2 composite film under UV light irradiation was investigated and compared with those of neat PVC, PVC – PEO and PVC – TiO2, by UV–Vis spectroscopy, weight loss analysis, Scanning electron microscopy and Fourier transform infrared. Composites of PVC – TiO2 and PVC – PEO – TiO2 were prepared with 0.1–3 %wt of TiO2 and 1–10 %wt of PEO. The photodegradation rate was accelerated as amount of TiO2 incorporate was increased from 0.1–3 %wt due to a higher interaction among TiO2 particle with polyvinyl chloride chains. In the same way, results show that the degraded PEO produced an acid and an aldehyde, which were able to facilitate PVC degradation. The morphologies of the composite film before irradiation are smooth. After irradiation the composite films are obviously decomposed. It shows that the cavity size and depth of PVC – PEO – TiO2 film is much larger than the other film, the results confirm that the PEO promotes the degradation of PVC film.
