Enhancement on protonation (H+) with incorporation of flexible ethylene carbonate in CMC–PVA–30 wt % NH4NO3 film

In the present work, carboxymethyl cellulose (CMC)–polyvinyl alcohol (PVA)–NH4NO3 with addition of ethylene carbonate (EC) based polymer blend electrolyte (PBE) was explored. The complexes PBE EC revealed that an interaction –OH and –COO? CMC–PVA dissociation H+ from NH4NO3 provides a flexibility pathway for ion hopping. optimum ionic conductivity at room temperature found to be 3.92 × 10?3 S/cm sample containing 6 wt.% increment amorphous phase thermal stability. Based on Impedance-Nyquist theoretical approach, it shown cation transference number (tH+= 0.48) is primarily influenced by mobility as well ions diffusion coefficient. findings verified CMC–PVA–NH4NO3–EC possesses favorable conduction properties upon physical structural modification promising electrolyte.
