摘要:

杜仲胶(EUG)主要由反式聚异戊二烯组成,是一种具有良好生物相容性、橡塑二重性和优异力学性能的天然高分子材料。近年来,EUG在新型生物基材料领域备受瞩目。EUG在室温下结晶度高,表现为刚性塑料状态,极大程度限制了其在功能材料领域的应用。因此,将EUG进行物理或化学改性,进而拓宽其应用范围已成为近年来的研究热点。本文详细介绍了EUG分子链结构特点,随后从物理改性和化学改性两个方面系统论述了EUG常见的改性方法及机理,如通过与其它材料共混或环氧化改性、硫化改性等改变EUG的硬度及弹性。对EUG在绿色轮胎与公路建设、形状记忆与自修复材料、减震与吸声材料、医用材料、生物降解复合材料等新型功能材料领域的最新研究进展进行了综述,并在此基础上展望了EUG在生物基高性能材料领域的发展前景。

Abstract:

Eucommia ulmoides gum(EUG) is a kind of natural polymer material with good biocompatibility, excellent rubber-plastic duality, and good mechanical properties, which has attracted much attention in the field of novel biomaterials in recent years. However, the poor elasticity and miscibility at room temperature have greatly limited its application in the field of functional materials. Therefore, the physical or chemical modification of EUG for broadening its range of applications has become the research hotspot. Combining with the structural characteristics of EUG, the common modification methods, formation mechanism and material properties of EUG by physical and chemical modification were firstly summarized, such as changing the hardness and elasticity of EUG by blending with other materials or epoxidation modification, vulcanization modification, etc. Then, the latest applications of EUG in green tire and road construction, shape memory and self-healing materials, anti-vibration and sound absorption, medical materials, and biodegradable composite are introduced, respectively. Finally, we envision that the EUG will play an increasingly important role in polymer science in future.

Key words: Eucommia ulmoides gum, blending, graft modification, shape memory, self-healing
