摘要

研究了水溶性偶氮苯单体4-[4-(丙烯酰氧基)苯基偶氮]苯磺酸（APABS）的光物理性质。考察了溶剂对其光异构化反应的影响，并将APABS和丙烯酸羟乙酯（HEA）组成共聚体系，在交联剂N, N-亚甲基双丙烯酰胺（MBAA）的存在下，通过光聚合方法制备水凝胶。利用扫描电子显微镜考察了聚合温度对水凝胶内部结构影响。

Abstract

The photo-physical properties of the water-soluble substituted azobenzene monomer, 4-[4-(acryloyl)phenylazo]benzene sulfonic acid (APABS), have been studied, and the effects of the solvent on its photo-isomerization performance were investigated. With N, N′-methylenebis acrylamide (MBAA) as cross-linking agents, the copolymer hydrogels of APABS and HEA were prepared through photo-polymerization method. The effects of the polymerization temperature on the interior morphology of hydrogels have been examined by scanning electron microscopy (SEM).
