HNTs-MPC/PES杂化超滤膜制备及其性能研究
Preparation and antifouling property of polyethersulfone ultrafiltration hybrid membrane by blending with halloysite nanotubes grafted with MPC
通过反向原子转移自由基聚合(RATRP)的方法在埃洛石纳米管(HNTs)表面接枝2-甲基丙烯酰氧乙基磷酸胆碱(MPC)制备纳米复合材料(HNTs-MPC),并将其与聚醚砜(PES)共混制备PES杂化超滤膜以期提高膜的抗污染性能。通过FT-IR、TG、TEM对改性前后的HNTs进行了分析表征,结果证明了MPC成功接枝在HNTs表面,接枝量为0.052 g (MPC)/g (HNTs)。实验结果表明:与PES空白膜相比,改性后的杂化膜纯水通量更大,亲水性更强,并且随着HNTs-MPC含量的增加其皮层更薄。动态超滤实验表明杂化膜具有较高的通量恢复性能以及抗蛋白质污染性能。
HNTs-MPC composites were successfully synthesized via reverse atom transfer radical polymerization (RATRP), and then incorporated into polyethersulfone (PES) matrix to fabricate hybrid membranes via phase inversion for endowing membranes with antifouling property. The raw HNTs and modified HNTs were characterized by FT-IR,TG and TEM. The results showed that HNTs-MPC was successfully synthesized, and the grafted amount of MPC was 0.052 g (MPC)/g. The hybrid membranes were shown to be more hydrophilic, which corresponded to a higher pure water flux. The skin layer of hybrid membrane became slightly thinner than bare membrane with increasing the content of HNTs-MPC composites. Protein ultrafiltration experiment also indicated that the antifouling ability and flux recovery performance of the hybrid membranes were superior to bare PES membranes.
