以环氧大豆油（ESO）和聚己内酯（PCL）为原料合成了植物油基形状记忆材料。在聚己内酯（PCL）存在下，通过酸催化固化合成了PolyESO/PCL复合材料。在反应过程中，PCL几乎不与ESO反应，PCL组分的结晶度降低，形成半互穿网络结构。PCL组分的掺入提高了基于ESO的网络聚合物的最大断裂应力和断裂应变。聚ESO/PCL在假单胞菌脂肪酶的作用下逐渐降解。此外，聚ESO/PCL具有良好的形状记忆性能，且其应变固定性取决于ESO和PCL的投料比。形状记忆-恢复行为具有可重复性。该材料有望为生物降解智能材料的发展做出贡献。
This article deals with the synthesis of plant oil-based shape memory materials from epoxidized soybean oil (ESO) and polycaprolactone (PCL). PolyESO/PCLs were synthesized by an acid-catalyzed curing in the presence of PCL. During the reaction, PCL scarcely reacted with ESO and the crystallinity of the PCL component decreased to form a semi-interpenetrating network structure. The incorporation of the PCL components improved the maximum stress and strain at break of ESO-based network polymer. The polyESO/PCL was gradually degraded by Pseudomonas cepasia lipase. Furthermore, the polyESO/PCLs exhibited excellent shape memory properties, and the strain fixity depended on the feed ratio of ESO and PCL. The shape memory-recovery behaviors were repeatedly practicable. The resulting materials are expected to contribute to the development of biodegradable intelligent materials.
