摘　　要：环氧树脂具有机械强度高、收缩性小、加工性能好、吸水率低等特点,被广泛应用作防腐涂料、电气绝缘材料、纤维增强复合材料。环氧树脂基复合材料已成为工业领域中不可缺少的基础材料。但环氧树脂脆性大、耐冲击性差且容易开裂的缺点在很大程度上限制了它在很多领域中的应用。本文综述介绍了近年来有关环氧树脂的改性方法及其增韧效果,重点介绍了通过可回收利用的生物基资源增韧环氧树脂的方法。Epoxy resin has been widely used in anticorrosive coatings,electrical insulation materials,fiber reinforced composites due to its high mechanical strength,small shrinkage,good processing performance and low water absorption.Epoxy resin matrix composite has become an indispensable basic material in various industrial fields.However,some disadvantages of epoxy resin,such as high embrittlement,poor impact resistance and easy cracking,severely limit its application.This work reviews the recent progress of modification methods and toughening effects of epoxy resins,while highlights those modification methods using recyclable biological resources.
