Abstract

The present disclosure relates to the field of shape memory materials, it discloses a betaine-based shape memory polymer and the preparation method thereof. The polymer is formed through free radical polymerization of an unsaturated betaine monomer, an acrylic monomer, and an ethylene glycol divinyl ether monomer with the addition of an initiator. The betaine-based shape memory polymer has thermosensitive shape memory property and wet sensitive shape memory property, and it has good biocompatibility and an excellent shape memory property, antibacterial property. It is of great potential for use in engineering, construction, daily life and medical service.
