| 摘要 |
The present invention relates to the field of shape memory materials, and disclosed are a betaine-based shape memory polymer and a preparation method therefor. The polymer is prepared by free radical polymerization of functional monomers such as an unsaturated betaine monomer, an acrylic monomer, an ethylene glycol divinyl ether monomer and the like, under the action of an initiator. The betaine-based shape memory polymer prepared has a thermal induced shape memory performance and a humidity sensitive shape memory performance, meanwhile, it also has a better antibacterial performance and a good biocompatibility. The shape memory polymer has a huge application potential on aspects, such as engineering, building, daily life, and medicine, etc. |
