چکیده
Proton conductivity of proton exchange membranes is the determining factor of performance and efficiency for the related energy conversion, harvesting, and storage systems. The presence of both sulfonated and fluorinated groups in the structure of polymer is proposed to achieve improved conductivity and stability, simultaneously. Applying theoretical assessment techniques will be also useful to design a high performance membrane. To this end, proton conductivity of membrane samples based on sulfonated/fluorinated polysulfones are studied using artificial neural network (ANN). Fluorinated regions are put in the composition of sulfonated polymers via three strategies including synthesis of sulfonated/partially fluorinated polymers, blending sulfonated and fluorinated polymers, and composite membranes of electrospun fluorinated mat impregnated with a sulfonated matrix. Sulfonation degree (WR_S), content of fluorinated groups (WR_F), and the trend of membrane cost are studied asdetermining factors of conductivity. According to ANN, there is a direct relationship between WR_S with proton conductivity. Regarding WR_F, the optimal value must be allocated to achieve suitable conductivity. Membrane cost including WR_S, WR_F, and diol structure has the highest impact on proton conductivity.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.
