| 中文摘要: |
| 聚乳酸（PLA）是一种绿色高分子材料，原料来源充足、无污染且可被生物降解。同时，PLA还具有良好的机械性能和物理性能，易被加工制作成膜。纳米纤维素（NC）也是一种天然的可再生资源，来源广泛、机械强度好且刚度高。将NC加入到PLA中制备复合薄膜可大幅提高复合薄膜的机械性能；但两者的界面相容性差，从而影响PLA-NC复合薄膜的机械性能。根据近几年国内外的研究文献，本文综述了PLA-NC复合薄膜的制备工艺、界面相容性的改善方法及其应用。 |
| Abstract: |
| Poly（lactic acid） （PLA） is a green polymer which has abundant sources of raw materials， and can be biodegraded completely by organisms. Meanwhile， poly（lactic acid） has good mechanical properties and physical properties， and it is easy to be processed into films. Nanocellulose （NC） is a kind of natural renewable resource with rich sources. Its mechanical strength and stiffness are very high. Nanocellulose can be used to increase the mechanical properties of poly（lactic acid） films， and the composite films have a wide range of applications and development prospects in various fields. But poly（lactic acid） is a hydrophobic material， nanocellulose is a hydrophilic material， and the mechanical properties of the films will be influenced by their poor interfacial compatibility. In this paper， the preparation methods and applications of poly（lactic acid）-nanocellulose composite films and the methods to improve their interfacial compatibility were summarized． |
