Abstract: The TiO₂-linear low density polyethylene (LLDPE)-g-maleic anhydride (MA)/low density polyethylene (LDPE) film with photocatalytic degradation property was prepared by blending LLDPE-g-MA. The SEM, XRD and FT-IR were employed to characterize the properties of the prepared TiO₂-(LLDPE-g-MA)/LDPE samples. The prepared TiO₂-(LLDPE-g-MA)/LDPE film possesses higher elongation which could be attributed to the promoted the interphase force between the nanoTiO₂ and LDPE. The SEM images demonstrate that the agglomeration of nanoTiO₂ is obviously reduced. Therefore, the nanoTiO₂ with higher dispersibility performs higher photocatalytic degradation efficiency and causes higher mass loss of TiO₂-(LLDPE-g-MA)/LDPE film.
