杜仲胶的基础与应用研究进展

Progress of Basic and Applied Research of Eucommia Ulmoides Gum

杜仲胶(EUG)是从杜仲植物组织中提取的一种天然材料,是我国特有的天然高分子材料。EUG的主要成分为反式-1,4-聚异戊二烯,分子主链含有双键,EUG可进行交联与化学改性,同时因具有良好的结晶能力和独特的橡塑二重性,EUG在航空航天、国防、医疗、交通、体育和建筑等领域具有广阔的发展前景。本文介绍基于EUG的结晶特性,EUG在共混材料、自修复材料、阻尼材料、液体橡胶材料、涂料、形状记忆材料、电磁屏蔽材料、吸声材料等中的应用及其研究进展,指出EUG在新材料领域的发展方向。

Eucommia ulmoides gum(EUG)is a natural material extracted from Eucommia ulmoides plant tissues and a unique natural polymer material in China.The main component of EUG is trans-1,4-polyisoprene,with double bonds in the main molecular chain.EUG can be crosslinked and chemically modified.At the same time,due to its good crystallization ability and unique rubber-plastic duality,EUG has broad development prospects in the fields such as aerospace,national defense,medical,transportation,sports and architecture.Based on the crystallization characteristics of EUG,this paper introduces the application and research progress of EUG in blended materials,self-healing materials,damping materials,liquid rubber materials,coatings,shape memory materials,electromagnetic shielding materials and sound absorption materials,and points out the development directions of EUG in the field of new materials.
