PROTON-CONDUCTING COMPOSITE POLYMER MATERIAL Russian patent published in 2014 - IPC C08L29/04 B01D71/38 H01G9/25 H01M8/02 

FIELD: chemistry.

SUBSTANCE: described is a proton-conducting composite polymer material which includes a linear polymer matrix which is a 2-9% aqueous solution of polyvinyl alcohol, containing silver nanoparticles with size of 20-100 nm in concentration of 40-100 mg/l and a proton-conducting solid electrolyte dispersed therein in the form of a phosphoric-tungstic acid and a plasticiser in the form of glycerine, with the following ratio of components, wt %: aqueous solution of polyvinyl alcohol 38-69, phosphoric-tungstic acid 19-50, glycerine - the balance.

EFFECT: proton-conducting composite polymer material having high ion conductivity and the lowest possible electronic component of conductivity, which improves power characteristics of supercapacitors or other solid-state electronic devices, and longer charge storage duration thereof.
