Medientyp: E-Artikel Titel: Enhancement of photocatalytic degradation of poly(vinyl chloride) with perchlorinated iron (II) phthalocyanine modified nano‐TiO2 Beteiligte: Fa, Wenjun; Gong, Chuqing; Tian, Lihong; Peng, Tianyou; Zan, Ling Erschienen: Wiley, 2011 Erschienen in: Journal of Applied Polymer Science, 122 (2011) 3, Seite 1823-1828 Sprache: Englisch DOI: 10.1002/app.34230 ISSN: 0021-8995; 1097-4628 Schlagwörter: Materials Chemistry ; Polymers and Plastics ; Surfaces, Coatings and Films ; General Chemistry Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p>A novel photodegradable thin film of poly(vinyl chloride) (PVC) composite was prepared by embedding modified TiO<jats:sub>2</jats:sub> nanoparticles into the commercial PVC. The photocatalyst nanoparticles were modified with perchlorinated iron (II) phthalocyanine (FePcCl<jats:sub>16</jats:sub>) to improve their photocatalytic activity. Solid‐phase photocatalytic degradation of the PVC‐FePcCl<jats:sub>16</jats:sub>‐TiO<jats:sub>2</jats:sub> 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<jats:sub>2</jats:sub> (PVC‐TiO<jats:sub>2</jats:sub>) 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<jats:sub>16</jats:sub>‐TiO<jats:sub>2</jats:sub> composite film was significantly higher than that of pure PVC film and PVC‐TiO<jats:sub>2</jats:sub> composite film under UV or sunlight irradiation. The photocatalytic degradation mechanism was discussed briefly. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011</jats:p>
