Abstract A simple and effective method to incorporate catalytic activity to a hollow fiber membrane is reported. Polyetherimide hollow fiber membranes were coated with a solution containing carboxyl-functionalized multi-walled carbon nanotubes and poly(ether- b -amide). Electron microscopy images confirmed the presence of a layer of percolating carbon nanotubes on the surface of the membranes. Cyclic voltammetry and linear swept voltammetry experiments showed that these membranes are able to drive the reactions of hydrogen evolution, and oxygen reduction, making them a cheaper, and greener substitute for platinum based cathodes in microbial bioelectrochemical systems. Water flux and molecular weight cut off experiments indicated that the electrochemically active coating layer does not affect the ultrafiltration performance of the membrane.

基于聚（醚-b-酰胺）/碳纳米管的电化学活性聚合物中空纤维

摘要 报道了一种将催化活性引入中空纤维膜的简单有效的方法。聚醚酰亚胺中空纤维膜涂有含有羧基官能化多壁碳纳米管和聚（醚-b-酰胺）的溶液。电子显微镜图像证实膜表面存在一层渗滤碳纳米管。循环伏安法和线性扫描伏安法实验表明，这些膜能够驱动析氢和氧还原反应，使其成为微生物生物电化学系统中铂基阴极的更便宜、更环保的替代品。水通量和截留分子量实验表明，电化学活性涂层不影响膜的超滤性能。
