摘要:
    探讨错流过滤中聚四氟乙烯微孔膜亲水性与抗污性的关系。在聚四氟乙烯（PTFE）膜表面引入磺酸基（-SO3H）,通过扫描电镜（SEM）、傅里叶红外光谱（FTIR）、固体表面电位分析仪（SurPASS）等研究-SO3H含量对膜亲水性、Zeta电位、牛血清蛋白（BSA）静态吸附量及水通量的影响。结果表明：疏水的PTFE膜易吸附负离子，Zeta电位<0，BSA吸附量高，水通量降幅大，抗污性差；经过亲水改性后，由于-SO3H的引入，膜表面不易吸附负离子，Zeta电位升高，BSA吸附量降低，水通量降幅小；随-SO3H含量增加，膜Zeta电位因-SO3H电离而降低，与负电性BSA之间的静电斥力增强，抗污性进一步提高。
