Abstract

Proton-conducting poly(acryl amide) hydrogels are prospective materials for application in electrochemical devices working at ambient temperatures. In the present paper, the conducting properties of hydrogels doped with H3PO4 or H2SO4 are analysed in connection with such features of the hydrogel membrane as sorption and permeation of solvents and tensile strength. It is shown that these features depend on the concentration of the acid used as protonic dopant as well as on the composition of the hydrogel membrane, i.e. the amount of crosslinking and gelation agents used in the gel synthesis.
