摘要:

目的综述了近几年来有关半纤维素改性、材料制备及其应用方面的研究，以期为半纤维素基薄膜材料的进一步开发与应用提供参考。方法通过收集与整理相关文献，阐述半纤维素的结构特点和分离提取方法，综述近些年来关于半纤维素包装薄膜材料的研究进展，并对比分析物理改性与化学改性2种改性方法对半纤维素薄膜材料包括阻隔性能、力学性能等的调控。结论对半纤维素进行物理或者化学改性，在保留原有优势性能的同时赋予半纤维素薄膜材料更好的机械强度、柔韧性、热稳定性以及疏水性等性能，符合半纤维素高值化利用新趋势。

Abstract:

Hemicelluloses, the second largest natural polysaccharide in nature, has wide raw material source, good biocompatibility, biodegradability and renewability, which shows broad application potential in packaging area in this paper. The paper aims to review the research on modification of hemicelluloses, preparation of hemicelluloses-based materials and its applications to provide reference for the further development and application of hemicelluloses films. The structural characteristics and extraction methods of hemicelluloses were described, and the research progress of hemicelluloses-based packaging films was reviewed. Moreover, the effects of physical and chemical modifications on the barrier properties and mechanical properties were compared and analyzed. After modifications, the mechanical strength, flexibility, thermal stability and hydrophobicity of hemicelluloses are improved, which is in line with the new trend of high value-added utilization of hemicelluloses.

Key words: hemicelluloses functional modification film packaging
