摘要: Abstract The novel single-ionic conductive gel polymer electrolyte was prepared from polyvinylidene fluoride (PVDF), propylene glycol carbonate (PC) and a new fluorine-containing ionomer. Cation–carbonyl interaction behavior, morphology ionic properties of this were studied by infrared spectra analysis (IR), nuclear magnetic resonance (NMR), differential scanning calorimetry (DSC), electron microscopy (SEM) complex impedance analysis. results showed that the ionomer miscible with both PVDF PC, carbonyl groups in PC could bond competitively cation. Both content had great effect on samples. For electrolyte, an conductivity above 10 −4 S cm −1 at room temperature be reached, system kind transport number sodium ion exceed 0.99 ( t + >0.99).
