摘　　要：[Objective] The aim was to research the influences of different formulations on oxidation resistance of PVDF hollow fiber membrane.[Method]The immersion precipitation phase inversion method was employed to make casting solution with different formulations into hollow fiber membrane.The membrane was immersed in 1% NaClO solution for testing its performance changes.[Result]The membrane made by materials with bigger molecular weight had better oxidation resistance performance;the surfactant tween-80 could increase water flux,but lead to lower rupture intension;Pore-forming agent PEG400 do better than PVP in the oxidation resistance of membrane.[Conclusion]This study will provide a good idea for the development of the PVDF membrane with high oxidation resistance.[目的]研究不同配方对聚偏氟乙烯(PVDF)膜抗氧化性能的影响。[方法]用浸没沉淀相转化法将不同配方的铸膜液纺制成中空纤维膜,并用1%NaClO溶液浸泡,测试其性能变化情况。[结果]分子量更大的膜材料PVDF(6020)制得的膜抗氧化性能更好;表面活性剂tween-80对通量提升明显,但断裂强度有所下降;成孔剂PEG400对膜的抗氧化性作用好于PVP。[结论]该研究为研制高抗氧化性的膜提供了很好的思路。
