With the renewability, functionality, and biocompatibility of Eucommia ulmoides gum (EUG), shape memory polymers fabricated from EUG present the potential application in biomedical devices and sensors. In this study, heat‐responsive shape memory composites were developed and reinforced by zinc dimethacrylate (ZDMA). ZDMA particles were in situ polymerized and uniformly dispersed in the EUG, showing strong interfacial interactions with EUG. The obviously improved tensile strength and storage modulus in the elastic state are attributed to the reinforcement of poly‐ZDMA particles. The switching temperature of EUG/ZDMA composites changed from 50 to 29°C through altering the dicumyl peroxide and ZDMA loading. The EUG/ZDMA composites exhibited high shape fixity of 95% and shape recovery of 90%, which favors theirs biomedical applications.

二甲基丙烯酸锌增强的热响应形状记忆杜仲胶复合材料

杜仲具有可更新性，功能性和生物相容性由EUG制成的口香糖（EUG），形状记忆聚合物目前在生物医学设备和传感器中的潜在应用。在这项研究中，开发了热响应形状记忆复合材料并通过二甲基丙烯酸锌（ZDMA）进行了增强。ZDMA颗粒在原位聚合并均匀分散在EUG中，显示出与EUG的强界面相互作用。弹性状态下抗张强度和储能模量的明显改善归因于聚ZDMA颗粒的增强。通过更改过氧化二枯基和ZDMA的负载量，EUG / ZDMA复合材料的转换温度从50°C变为29°C。EUG / ZDMA复合材料显示出95％的高形状固定性和90％的形状恢复性，这有利于其生物医学应用。
