摘要

A new material for proton conducting electrolyte base on sulfonated poly(vinylidene flouride- hexafluoropropylene) (PVDF-HFP)/1H-1,2,4-Triazole (TriA) membrane operating at low relativehumidity and has capability to self-humidify were investigated. Different concentrations of TriA andsulfamic or amidosulfonic acid (H3NSO3) in PVDF-HFP were prepared. The pores of a porous PVDF- HFP were packed with proton carrier, TriA and sulfamic acid (SFA). The samples were then exposedto -rays of up to 50 kGy. The effects of high energy -rays irradiation onto these proton conductingmembranes have been observed. The surface morphology was analysed by scanning electronmicroscopy (SEM). The ionic conductivity of the irradiated membrane was determined using o o impedance spectroscopy (IS) at different temperatures between 30 C and 100 C. The results showedthat the pores membranes shrinkage after irradiation and proton conductivity of the membraneincreased when the absorbed dose up to 30 kGy and after which the proton conductivity decreasedwith increasing of absorbed dose.
