麻纤维/可降解聚合物复合材料研究进展

Recent Advances in Research of Hemp Fiber Cellulose/Degradable Polymer Composites

随着化石资源的枯竭和传统塑料使用带来的环境问题日益严重,可生物降解的聚合物材料越来越受到人们的关注。目前可降解聚合物的力学性能与传统塑料相比仍然存在一定差距,限制了其应用与发展。将麻纤维加入到可降解聚合物中可以降低复合材料的脆性,提高材料的强度及热稳定性,增强阻隔性能。本文综述了近年来基于不同麻纤维/可降解聚合物复合材料的制备方法、应用和性能增强机理研究,同时指出了目前研究中存在的问题和未来的研究发展方向。

With the depletion of fossil resources and the increasing environmental problems caused by using traditional plastics,biodegradable polymer materials are attracting more and more attention.The applications and development of degradable polymers are limited by their lower mechanical properties relative to traditional plastics.The addition of hemp fiber to degradable polymers can reduce the brittleness,improve the strength,promote the thermal stability,and enhance the barrier properties of materials.In this paper,the preparation methods,applications,and performance enhancement mechanisms of different hemp fiber/degradable polymer composites in recent years are reviewed,and the problems existing in the current research and the future research development directions are pointed out.
