壳聚糖作为一种天然的氨基多糖,拥有良好的生物相容性和资源可再生性,但是较差的力学性能限制了其更广泛的应用。本研究以丙烯酸、N-乙烯基吡咯烷酮和丙烯酸-N-琥珀酰亚胺酯为单体聚合得到三元共聚物大分子交联剂,然后将其与壳聚糖溶液混合后制备壳聚糖水凝胶。采用红外、热重、SEM等对合成的聚合物及壳聚糖凝胶的组成、形貌和热稳定性进行了表征。结果表明,丙烯酸-N-琥珀酰亚胺酯共聚物的数均分子量为111900,具有一定的水溶性,与壳聚糖形成的水凝胶有良好的力学性能、溶胀性能和水蒸气渗透速率。在PBS(pH=7.4)中交联的凝胶膜与酸性条件下制备的凝胶膜相比,热分解温度提高,水接触角变大,力学性能得到较大提升。细胞毒性实验表明壳聚糖凝胶有良好的生物相容性,人脂肪干细胞在壳聚糖凝胶膜上会形成细胞簇并分泌外泌体。将壳聚糖凝胶膜覆盖在脂肪干细胞上,细胞能正常生长并分泌外泌体。因此,壳聚糖凝胶具有负载外泌体后应用于皮肤敷料的潜力。
