摘要: Abstract In this research polyvinyl chloride/multi walled carbon nanotube–co-copper nanolayer composite nanoparticles heterogeneous cation exchange membranes were prepared by solution casting techniques. The MWCNT–co-Cu magnetron sputtering method. effect of nanoparticle concentration on physico-chemical properties was studied. SEM, TEM and XRD results showed uniform distribution crystalline structure for the deposited Cu MWCNTs' surface. SOM images also relatively particle membranes. membrane potential, transport number, selectivity electrical conductivity improved an increase additive content in Membrane average roughness decreased slightly concentration. ionic permeability flux initially ratio up to 0.5 wt.% then increasing trend more Furthermore, mechanical stability matrix. Also, modified containing 4 wt.% better electrochemical compared other membranes, pure MWCNTs unmodified ones.
