While electroless nickel plating is considered as a promising candidate for fabrication of metallized polymer composite membranes with high performance, it suffers from problems of complex and high-cost pretreatment procedure, hindering its large-scale implementations. It is hypothesized that, inkjet printing integrated with electroless plating (ELP) can serve as a facile and economical membrane fabrication method to overcome above problems. The new method proposed in this study was processed by inkjet printing silver ions and pyrrole inks as catalytic layer followed by electroless Ni deposition on polypropylene (PP) membrane surface. Successful modification was verified by characterizing the surface morphology and elemental compositions of the membranes. In comparison to the pristine PP membrane, the PPy-Ag/Ni modified membrane demonstrated lower surface resistance (2.3 Ω), better hydrophilicity (44.9°) and higher pure water flux (1135.1 L m-2 h-1). When applying an external electric field (10.0 V cm-1), the average flux of the PPy-Ag/Ni membrane for yeast filtration increased from 107.8 to 137.7 L m-2 h-1, which was about 2.0 times higher than that of the pristine PP membrane. Meanwhile, the PPy-Ag/Ni membrane possessed a maximum flux recover rate when applied with an external electrical field. This work provided a facile and efficient approach for fabrication of composite conductive membranes.

喷墨印刷辅助化学镀镍，以制造具有改进性能的镍涂层聚丙烯膜。

尽管化学镀镍被认为是制备具有高性能的金属化聚合物复合膜的有前途的候选者，但是它遭受复杂且高成本的预处理过程的问题，从而阻碍了其大规模实施。假设，与化学镀（ELP）集成的喷墨印刷可以用作克服上述问题的简便且经济的膜制造方法。本研究中提出的新方法是通过喷墨印刷银离子和吡咯油墨作为催化层，然后在聚丙烯（PP）膜表面化学沉积镍进行处理的。通过表征膜的表面形态和元素组成，验证了成功的修饰。与原始PP膜相比，PPy-Ag / Ni改性膜表现出较低的表面电阻（2.3Ω），较好的亲水性（44.9°）和较高的纯水通量（1135.1 L m-2 h-1）。当施加外部电场（10.0 V cm-1）时，用于酵母过滤的PPy-Ag / Ni膜的平均通量从107.8增加到137.7 L m-2 h-1，这是酵母滤膜的平均通量的2.0倍。原始的PP膜。同时，当施加外部电场时，PPy-Ag / Ni膜具有最大的通量回收率。这项工作为复合导电膜的制造提供了一种简便而有效的方法。8至137.7 L m-2 h-1，约为原始PP膜的2.0倍。同时，当施加外部电场时，PPy-Ag / Ni膜具有最大的通量回收率。这项工作为复合导电膜的制造提供了一种简便而有效的方法。8至137.7 L m-2 h-1，约为原始PP膜的2.0倍。同时，当施加外部电场时，PPy-Ag / Ni膜具有最大的通量回收率。这项工作为复合导电膜的制造提供了一种简便而有效的方法。
