摘要

聚乳酸因具有优良的生物相容性、易降解、强度高，可塑性强，易加工成型等优点，近年来倍受高分子材料行业的青睐。但是由于存在脆性高、热性能较差、降解速度不易控制等缺陷，限制了使用效果，因此需进行改性研究。植物纤维质轻、价廉、比强度高并可降解，近年来作为增强材料发展迅速，用来增强聚乳酸，不但可以提高材料的性能，而且赋予复合材料完全降解性能。植物纤维增强聚乳酸复合材料可称为“绿色复合材料”，可以有效地缓解环境问题及能源危机的冲击。本文就现阶段植物纤维增强聚乳酸的研究状况，围绕复合材料的界面改善、冲击性能、热性能的提高和复合工艺的改进等几个关键问题，展开了详细讨论，并对近年来较热门的纤维素微原纤增强聚乳酸纳米复合材料进行了简单总结。

Abstract

Poly(lactic acid) has won the polymer industria'l's high favor due to its merits of excellent biocompatibility

biodegradability

high strength

workability and plasticity in recent years.But it also has the defects of brittleness

poor heat resistance and unstable degradation rate

for this reason its application is restricted and needs to be modified.Plant fiber developed rapidly in recent years because of the benefits of its low density

low cost

high specific strength and biodegradability.As the reinforcement

it can not only improve the properties of the materials

but also endows the composite with fully-biodegradability.The plant fiber reinforcing poly (lactic acid)(PLA) composite could be named "green composite"

it represents an opportunity to partially ameliorate the environmental impacts and energy crisis.The recent researches of plant fiber reinforcing PLA composites were reviewed in this paper.Several pivotal questions were discussed in detail:improving of the interface

impact strength

heat resistance and processing method of the composites.The microfibrillited cellulose (MFC) reinforcing PLA nano-composites were also discussed.
