| 摘 要： | 本文采用紫外光照射接枝的方法将聚乙二醇甲基丙烯酸甲酯(PEGMA)亲水单体接枝在疏水性聚偏氟乙烯(PVDF)超滤膜表面,改善PVDF膜的亲水性能.实验中以N,N-亚甲基双丙烯酰胺(MBAA)为交联剂作为对比,发现添加MBAA可以减少PEG接枝层的溶胀性.本实验研究不同改性条件对膜性能的影响,利用表面接触角(CA)、红外光谱分析(ATR-IR)、扫描电镜(SEM)等手段表征膜表面特征,同时研究了改性膜对乳化油和牛血清蛋白溶液分离效率和抗污染能力.实验结果表明,经改性后膜亲水性明显提高,对污染物的截留效果和抗污染能力均有所提高. |

| Abstract: | In this paper, the hydrophobic PVDF membranes were modified via UV-irradiation to graft the hydrophilic monomer poly(ethylene glycol) methacrylate (PEGMA) on the membrane surface, which can improve the hydrophilicity of the PVDF membrane. The addition of the N,N-methylene bisacrylamide (MBAA) as cross-linking agent was found to reduce the swelling of the PEG grafed-layer. The influence of the modification condition on membrane performance was investigated. The modified membranes were characterized with surface contact angle (CA), infrared spectroscopy (ATR-IR), scanning electron microscopy (SEM), and the filtration tests of emulsion. BSA solution were conducted to investigate the separation efficiency and anti-fouling ability of the modified membrane. The experimental results showed that the hydrophilicity and anti-fouling ability of the modified membranes were improved obviously. |
