Photodegradation Improvement of Low-Density Polyethylene Thin Film with gC₃N₄/5ZnO/TiO₂Photocatalysts

Abstract:

LDPE waste disposal is a critical issue nowadays and huge pile of this polymer represents a threat to the environment. Herein, gC₃N₄/5ZnO/TiO₂ photocatalysts (1 wt %) incorporated in LDPE film were investigated and compared with neat LDPE film. Tabletop scanning electron microscopy (SEM) micrograph showed the surface morphologies of neat and LDPE composite films before and after accelerated weathering. Experimental results on LDPE composite films after exposure to UV irradiation showed improvement in degradation rate (~0.274%/hour) in comparison to other study (0.225%/hour). Results of weight lost on LDPE composites after accelerated weathering test (~42.31%) also showed that the degradability increased with the decrease of thickness.
