Abstract
In this paper, a novel kind of photodegradable PVC-FePcCl(16) composite film was prepared by homogeneous embedding FePcCl(16) into the commercial PVC plastic. The photodegradation performance of as-prepared film has been investigated in the ambient air under UV light irradiation by means of weight loss monitoring, FT-IR spectroscopy, UV-Vis spectroscopy. In comparison with the pure PVC film, higher weight loss rate, increasing carbonyl peak intensity and accelerating dehydrochlorination were observed. These results indicate that the PVC-FePcCl(16) composite film has a higher photodegradation activity owing to the FePcCl(16). Moreover, FePcCl(16) has good photostability in the photoreaction. The possible photodegradation mechanism of PVC-FePcCl(16) composite film was also discussed.
