چکیده
In the current study nanocomposite polyvinyl chloride/multi walled carbon nano tubes-co-silver nanolayercomposite nanoparticles heterogeneous ion exchange membranes were prepared by solution casting techniques. TheMWCNTs-co-Ag nanolayer composite nanoparticles were prepared by magnetron sputtering method. The effect ofcomposite nanoparticles concentration on physico-chemical properties of membranes was studied. The SEM, TEMresults showed uniform distribution and crystalline structure for deposited Ag nanolayer/nanoparticles on theMWCNTs' surface. Membrane potential, transport number and selectivity were improved by increase of additivecontent in membrane matrix. The mechanical stability of prepared membranes was also improved by increase ofMWCNTs-co-Ag nanolayer composite nanoparticles ratio in membrane matrix. The modified membrane containing4%wt composite nanoparticles showed better electrochemical properties compared to others.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
