In this paper, we present an efficient and green extraction process for Eucommia ulmoides gum (EUG) to solve the tricky problems in separation and precipitation, providing a new idea for the industrialization of EUG extraction. Subsequently, the obtained EUG was blended with low density polyethylene (LDPE) and zinc methacrylate (ZDMA) to fabricate novel shape memory composites with both covalent and ionic crosslinking networks. It was found that the improvement in mechanical performance and enhancement in shape recovery ability of the EUG/LDPE/ZDMA composites was attributable to the Zn²⁺-based ionic crosslinks. The EUG/LDPE/ZDMA shape memory composites could be candidates in the production of medical fixing materials, hot-shrinkable tubes and packaging products. © 2021 Society of Chemical Industry

甲基丙烯酸锌增强生物基杜仲胶/低密度聚乙烯形状记忆复合材料

在本文中，我们提出了一种高效、绿色的杜仲胶（EUG）提取工艺，以解决分离沉淀中的棘手问题，为杜仲提取的产业化提供新思路。随后，将获得的 EUG 与低密度聚乙烯 (LDPE) 和甲基丙烯酸锌 (ZDMA) 混合，以制造具有共价和离子交联网络的新型形状记忆复合材料。结果表明，EUG/LDPE/ZDMA 复合材料力学性能的提高和形状恢复能力的增强归因于 Zn ²⁺基于离子交联。EUG/LDPE/ZDMA 形状记忆复合材料可用于生产医疗固定材料、热缩管和包装产品。© 2021 化学工业协会
