摘要/Abstract

摘要： 以N,N’⁃亚甲基双丙烯酰胺（MBA）为交联剂，丙烯酸十八酯（SA）为疏水性单体，甲基丙烯酸二甲氨基乙酯（DMAEMA）为亲水性单体，乙烯基卟啉（MTPP）为光热单体，通过自由基共聚合成功制备了具有红光响应性的PSDM⁃MTPP形状记忆水凝胶。结果表明，PSDM⁃MTPP水凝胶在较低的入射光强（<528 mW/cm2）与较短的辐照时间下便能回复至初始形状，并且能实现临时形状与初始形状之间多中间状态的保持及区域选择性回复。这种具备快速响应、高回复率、远程控制及空间选择性的形状记忆凝胶在生物医学领域具有潜在的应用价值。

Abstract: N,N'⁃methylenebisacrylamide (MBA) is used as a crosslinking agent, octadecyl acrylate (SA) is a hydrophobic monomer, and dimethylaminoethyl methacrylate (DMAEMA) is a hydrophilic monomer. Vinyl porphyrin (MTPP) is a photothermal monomer, and PSDM⁃MTPP shape memory hydrogel with red light responsiveness was successfully prepared by free radical copolymerization. The experimental results show that a low light intensity (<528 mW/cm2) and a short irradiation time can motivate the PSDM⁃MTPP hydrogel recover to original shape. Moreover, maintaining multiple intermediate states and regioselective responses. This shape memory gel with fast response, high recovery rate, remote control and spatial selectivity has potential application value in biomedical field. The obtained shape memory hydrogel with fast response, high recovery rate, remote control and spatial selectivity provided potential application in biomedical field.

Key words: Porphyrin, Stearyl acrylate, Red light photothermal effect, Shape memory hydrogel
