In this paper, we presented 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 network. It was found that the improvement in mechanical performances and enhancement in shape recovery ability of the EUG/LDPE/ZDMA composites were attributed 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, and packaging products.
