Preparation and physical properties of (PVA)0.75(NH4Br)0.25(H2SO4)xM solid acid membrane

Ion transport properties of magnesium bromide/dimethyl sulfoxide non-aqueous liquid electrolyte

“…Therefore, the possible reason of enhancement in conductivity at low concentration of MgBr 2 is due to generation/introduction of mobile charged species, namely Mg 2+ and Br − . The decrease in conductivity, observed after ∼0.16 M of MgBr 2 , is consistent with the higher viscosities of the more concentrated salt mixtures, and thus restricted free cation mobility (i.e., decrease of μ ), as a result, lower ionic conductivity is observed [16] , [18] , [19] .…”

Effect of polyacrylamide morphology templated using lyotropic liquid crystal on the proton conductivity of acid hydrogels

“…15 3 30 We believe that the hopping of protons between dissociated HSO 4 À anions via hydrogen bonding accounted for the observed conductivities. 31…”

Effect of Si and EC plasticizer on the ionic conductivity enhancement of (PVA). (NaHSO4) 0.5 solid polymer electrolyte

“…Additionally, they provide higher safety, prevent the build-up of internal pressure and can be designed in many desirable sizes and shapes. High ionic conductivity and low price are the favorable characteristics of polymer electrolyte membranes [3]. Solid acid membranes are a fascinating class of materials built upon hydrogen bonded oxyanion groups.…”

“…Solid acid membranes are a fascinating class of materials built upon hydrogen bonded oxyanion groups. These compounds conduct protons without the assistance of mobile water molecules, opening new technological possibilities and scientific avenues [3].…”

“…The essence of plasticization is to enhance the conductivity of polymer electrolyte by means of additives of low molecular weight and high dielectric constant such as propylene carbonate (PC) ethylene carbonate (EC) and poly ethylene glycol (PEG). The addition of plasticizers could enhance the conductivity and better contact between the electrolyte\electrode [3]. The role of plasticizer should be enhancement in the fraction of amorphous phase and increasing flexibility in the polymeric segments [4].…”
