摘要：

溶胶-凝胶法制得的TiO2经GO修饰，通过SEM、XRD分析表明制得的复合粒子为TiO2、GO的均匀混合物，且TiO2为易分散、粒径均匀的锐钛矿型。将其添加至PVDF铸膜液基体，采用相转换法制备TiO2/GO/PVDF改性复合膜。X射线衍射、红外光谱和接触角测试实验结果表明，TiO2/GO和PVDF有效结合，且在相转化过程中TiO2/GO转移至膜表面，复合膜表面的亲水性增强。借助SEM发现GO和TiO2间存在的协同作用使TiO2/GO /PVDF改性复合膜孔道和孔径均发生了改变。结合膜性能测试实验，证实其亲水性有较大提升，纯水通量上升至203.5 L.m-2.h-1，分别为纯PVDF膜、TiO2/PVDF膜的2.3倍和1.2倍。此外TiO2/GO粒子携带的负电荷增大其对污染物的静电斥力，对BSA的截留率高达91.2%，较纯PVDF膜和TiO2 /PVDF膜具有更优的抗污染性，通量恢复率可达86.3%。

TiO2 prepared by sol-gel method was modified by GO, by mieans of SEM and XRD analysis showed that the prepared composite particles were uniform mixture of TiO2 and GO, and TiO2 was anatase type with easy dispersion and uniform particle size. We successfully prepared a TiO2/GO/PVDF modified composite membrane by phase inversion method.X-ray diffraction、infrared spectrum and the results of the contact angle analysis showed that TiO2/GO and PVDF were well combined and the GO-TiO2 was transferred to the membrane surface, and the hydrophilicity of the composite membrane surface was enhanced.By means of SEM, it was found that the synergistic effect between GO and TiO2 changed both the channel and average pore size of
TiO2/GO/PVDF modified composite membrane. The combined membrane performance test proved that its hydrophilicity was greatly increased and the pure water flux was up to 203.5L.(M-2.h-1), which was 2.3 times that of pure PVDF membrane and 1.2 times that of TiO2/PVDF membrane,. The negative charge of TiO2/GO was found to increase the electrostatic repulsion of the pollutants. The hydrophilicity of the TiO2/GO /PVDF composite membrane was the highest. The retention rate of bovine serum albumin (BSA) was 91.2%. The TiO2/GO/PVDF composite membrane had a stronger antipollution performance compared with the unmodified and single ultrafiltration membranes, and the pollution recovery rate reached 86.3%
