초록

Photocatalytic decomposition of polyethylene film with TiO2 nanotube powders (NTs) was investigated under UV irradiation at ambient conditions. TiO2 NTs composed of individual nanotubes are prepared by rapid breakdown anodization technique. A comparative study on the photocatalytic decomposition of polyethylene-TiO2 composite films prepared using TiO2 nanoparticles (NPs) or TiO2 NTs (NTs), respectively, was conducted under UV irradiation. Polyethylene film incorporated with TiO2 NTs showed 26 wt% weight loss after 200 h under UV irradiation about two times faster decomposition rate than TiO2 NPs which is attributed to large surface area of TiO2 NTs.
