| 摘 要： | 采用溶胶-凝胶法（sol—gel）在聚乳酸（PLA）基膜上负载羟丙基甲基纤维素／二氧化硅（HPMC／SiO2）有机-无机杂化层，制备HPMC／Si02有杂化复合薄膜。表征和测试杂化复合薄膜的结构与性能。结果表明：当HPMC溶液体积分数为6％时，杂化复合薄膜的氧气阻隔性能比PLA薄膜的氧气阻隔性能提高了36倍，同时，杂化复合薄膜的拉伸强度优于PLA薄膜。

| Abstract: | Transparent HPMC/SiO2 inorganic-organic hybrid composite films, consisting of inorganic- organic hybrid composites on polylactic acid（PLA） film, are prepared via sol-gel process. The structure and properties of the hybrid composite films are inspected. The results show that when the volume ratio of HPMC solution to the hybrid sol is 6%, oxygen barrier of the hybrid composite films improved 32.3 times than PLA film. At the same time, tensile strength of the hybrid composite films are better than pure PLA film. |
