Abstract:

The TiO2 film was coated on poly vinyl chloride (PVC) surface by dip-coating process from TiO2-PVC-THF suspension. The morphology and crystal structure of the assynthesized samples were characterized by SEM and XRD. The photocatalytic properties were measured by the photodegradation reaction of RhB and the anti-adhesion and anti-bacteria for Escherichia coli. The results show that the resultant TiO2 film is well-conglutinated on PVC surface and has the same crystal structure as the original TiO 2 powder. The TiO2/PVC shows excellent photocatalytic activity for the degradation of aqueous RhB and the activity increases with increasing reaction time and tends toward stable after accumulative illumination for 11.5 h. The TiO2 film shows good bacterial anti-adhesion activity following photo-activation and sterilization property under UV irradiation. The E. coli can be killed completely after UV irradiation for 1.5 h. © 2008 Wiley Periodicals, Inc.
