摘要: 将锐钛矿TiO2纳米颗粒共混于铸膜液中, 用溶致相转换分离法制备了纳米TiO2改性PVDF膜, 并对复合膜的结构进行了表征, 研究了TiO2纳米粒子含量对复合膜性能的影响。结果表明, 随着TiO2纳米粒子含量的增加, 复合膜的表面水接触角降低、亲水性提高, 纯水通量逐渐增加(TiO2浓度<8%), 复合膜对于蛋白质吸附量降低、膜的抗污染能力提高。当LiCl的浓度(质量分数, 下同)为2%、PEG600的浓度为2%、PVDF的浓度为20%、TiO2的浓度为5%--8%时, 杂化膜的孔径大小均匀, TiO2颗粒负载于PVDF膜的骨架中。与PVDF膜比较, TiO2/PVDF复合膜的亲水性提高、对蛋白质的吸附降低、抗污染能力增强。此复合膜对Cu(II)表现出良好的吸附--脱附性能, 在150 min内对Cu(II) 的吸附率为82.19%。

Abstract:The hybrid membrane was prepared through reversed phase cast method by blending the anatase-TiO2 nanoparticles with the PVDF casting solutions. The metallographic microscope, scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR) were used to character the hybrid films, and the effects of TiO2 nanoparticle content on the properties of the TiO2/PVDF hybrid membraine were investigated. The results showed that a promoted adsorption and elution efficiencies of PVDF/TiO2 hybrid membranes were observed compared with that of the neat PVDF film. And with increase of TiO2 nanoparticle content, the surface water contact angle of the hybrid membraine decreases, the hydrophily, pure water flux (TiO2 nanoparticle content <8%) and the contamination resistance increase. The optimum conditions were determined as follows: w(LiCl)=2%, w(PEG600)=2%, w(PVDF)=20% and w(TiO2)=5%–8%.
