Study on PET/TiO2@Ag Blends with Low VOCs Content

doi:10.19491/j.issn.1001-9278.2020.05.006

Abstract

Abstract:

In this work, PET/TiO₂@Ag blends were prepared by melt blending, followed by Ag loading, and their thermal, mechanical and photocatalytic properties were investigated by DSC, electronic universal testing machine and UV?visible spectrophotometer. The results indicated that the blends achieved optimum thermal and mechanical properties at the nano?TiO₂ content of 3 wt%. The loading of Ag could significantly broaden the light response range of the blends. With an increase of Ag loading, the photocatalytic properties of the blends increased at first and then tended to decrease. The blends exhibited an optimum photocatalytic effect at the illumination time of 4 min. The content of VOCs in the blends decreased at first and then tended to increase with the illumination time and achieved a minimum value at 4 min.

Key words: poly(ethylene terephthalate), titanium dioxide, volatile organic compound, photocatalytic
