分别通过紫外和可见光引发光聚合技术设计并制备了两种不同类型的含偶氮基水凝胶。以利巴韦林为模型药物，所得两种水凝胶表现出不同的溶胀特性和控释行为。在额外的照射下，它们表现出不同的光响应特性，这可能是由于不同光照射下偶氮基团的不同异构体状态以及通过扫描电子显微镜（SEM）研究的水凝胶的内部形态所致。 (C) 2010 Elsevier B.V. 保留所有权利。
Two different types of hydrogel containing azo group were designed and prepared via UV and visible light initiating photopolymerization technology respectively. The obtained two hydrogel showed different swelling properties and control release behaviors with Ribavirin as model drugs. Upon additional irradiation, they exhibited different photo response characters, which may be due to the different isomer states of azo group under different light irradiations and the interior morphology of hydrogel investigated by scanning electron microscopy (SEM).
