摘要
利用戊二醛在成膜时使壳聚糖交联,形成壳聚糖/聚乙二醇半互穿网络,进一步抽提制得壳聚糖基多孔膜。多孔膜在溶液中有较好的化学稳定性,孔径尺寸在亚微米级别,可以通过改变交联剂用量得到不同孔结构的多孔膜。多孔膜对甲基橙和活性橙82有较好的吸附性,染料分子的极性基团越多,壳聚糖基多孔膜对其吸附能力越强。
Chitosan-base porous membranes have been prepared by selective dissolution of semi-IPN of chitosan/poly ethylene glycol blend membranes. The porous structure is determined by the amounts of crosslinking agent. The porous membrane has good absorption on the dyes, such as methyl orange and active orange 82. The absorption is influenced by the porous structure and the molecular structure of the dyes.
