%X Composite film which has self-degradation performance under UV light was prepared by blending nano-ZnO and polystyrene at high speed in this study. Analysis indicates that after adding the coupling agent KH570, nano-ZnO and PS were linked together through chemical bonding. The TG spectra showed that ZnO/PS composite film has higher heat resistant than pure PS. Also, SEM images indicated that 0.5 wt% nano-ZnO were evenly distributed in the PS membrane, however, light corrosion appeared on the membrane surface after UV irradiation. The UV irradiation experiments showed that for a 0.5 wt% ZnO/PS composite film, after 15 days at a UV irradiation power of 15 W, the degradation rate reached 3.715%.
