摘要：
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. (c) 2021 Society of Chemical Industry
