| 摘 要： | 利用纳米ZnO与聚苯乙烯(PS)高速共混法制备了一种在紫外光下具有自降解性能的复合薄膜.分析表明,经过KH570处理的纳米ZnO与PS通过化学键的方式桥联在一起.TG分析表明,复合薄膜的耐热性较PS有所提高；SEM图像显示0.5 wt％ ZnO在PS薄膜表面分布均匀,经过UV照射后薄膜表面出现光腐蚀现象.复合薄膜紫外光自降解实验表明:0.5 wt％ ZnO/PS薄膜在15W的紫外灯照射下,15d的自降解率为3.715％. |

| Abstract: | 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%. |
| Keywords: | nano-ZnO/polystyrene composite film self-degradation |
