以季铵化BPPO中空纤维膜为原料,通过sol-gel反应填充巯丙基三乙氧基硅烷(KH580),然后进行氧化,得到同时含有季铵和磺酸基团的杂化荷电镶嵌膜,阴离子交换容量(AEC)和阳离子交换容量(CEC)分别为1.57～1.76 mmol/g和1.07～1.24 mmol/g.对该膜进行了结构和物化性能的表征,然后进行蛋白质吸附和脱附.结果表明,与基膜相比,荷电镶嵌膜在溶胀度方面有所改进.pH=4、7和8时荷电镶嵌膜对牛血清蛋白(BSA)的吸附量较高,可达到20mg/g以上.在碱性条件下(pH=8),脱附率明显高于基膜,可以达到约95％.由此说明基于BPPO的荷电镶嵌中空纤维膜可以用作吸附材料.
