Study on Photo-Degradation of Poly(ethylene terephthalate)/SiO₂/TiO₂ Hybrid Composites by Sol-Gel Method under Ultraviolet Radiation

Abstract:

Poly (ethylene terephthalate) (PET)/SiO₂/TiO₂ hybrid composites were synthesized via the sol-gel method in the presence of tetraethylorthosilicate (TEOS) and tetrabutyltitanate (TBT). The formation of Si-O-Ti bonds in the resulting products was confirmed by Fourier transform infrared spectroscopy (FTIR) analysis. The Photo-degradation properties of hybrid composites were investigated under the ultraviolet radiation. And the change of the intrinsic viscosity for the hybrid composites was measured using an Ubbelohde viscometer after the photo-degradation.
