摘要
为了改善聚偏氟乙烯超滤膜的亲水性及抗污染性，本文采用共混的方法在聚偏氟乙烯中加入无机亲水型纳米SiO，，通过实验证明纳米SiOz的加入大大地提高了聚偏氟乙烯超滤膜的亲水性和抗污染性，而且封膜截留率影响不大。
In order to improve the hydrophilicity and anticontamination of PVDF UF membrane, SiO2/PVDF blending was introduced in this research. The results showed that the hydrophilicity and anticontamination of PVDF were improved considerably by blending with SiO2. Furthermore, the rejection of the membrane was little effect by this method.
