Investigation of the mechanical properties of composite polymer electrolytes based on CsH2PO4

The mechanical properties of the CsH2PO4 and hybrid compounds with different polymers (SKF-26, UPTFE, Butvar B-98) was determined by Vickers microhardness test for first time. It shown that increase in volume fraction polymer results low HV values corresponding to high robustness membranes plastic deformation. Mechanical depend on type best were obtained SKF-26. improvement makes investigated composite electrolytes promising use as proton-conducting medium-temperature range.
