英文摘要Photodegradable polypropylene (PP) composites were prepared via melting blending using PP and titanium dioxide (TiO2) immobilized organically modified montmorillonite (organoclay). TiO2 immobilized organoclay (TiO2-OMT) was synthesized by immobilizing anatase TiO2 nanoparticles on organically modified clay via sol-gel method. The structure and morphology of TiO2-OMT were characterized by XRD and scanning electron microscope (SEM), which showed that anatase TiO2 nanoparticles with the size range of 8-12 nm were uniformly immobilized on the surface of organoclay layers. Diffuse reflection UV-vis spectra revealed TiO2-OMT had similar absorbance characters to that of commercial photocatalyst, Degussa P25. The solid-phase photocatalytic degradation of PP/TiO2-OMT composites was investigated by FTIR, DSC, GPC and SEM. The results indicated that TiO2-OMT enhanced the photodegradation rate of PP under UV irradiation. This was due to that immobilization of TiO2 nanoparticles on organoclay effectively avoided the formation of aggregation, and thereby increased the interface between PP and TiO2 nanoparticles. After 300 h irradiation, the average molecular weight was reduced by two orders of magnitude. This work presented a promising method for preparation of environment-friendly polymer nanocomposites.
