“…A variety of semicrystalline and amorphous polymers, including poly (ethylene oxide) (PEO), poly(vinyl pyrrolidone) (PVP), poly(propylene oxide) (PPO), poly(vinylidene fluoride) (PVDF), poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), poly(methyl methacrylate) (PMMA), poly(acrylonitrile) (PAN), poly(vinyl chloride) (PVC), poly(vinyl alcohol) (PVA), and poly(propylene carbonate) (PPC) are most common and frequently utilized as host matrices in the preparation of high performance SPEs. 2,3,5,6,8,9,12,13,[15][16][17][18][19][20][21] The use of these different polymer matrices offers a large number of advantages in the SPEs development, ranging from their inherent flexibility, appreciable conductivity, thermal stability, and compatibility with other components of the electrochemical devices. 3,4,12,[16][17][18][19][20][21][22] Among the polymer choices, the use of the PEO matrix dominates owing to its high chain mobility, low melting temperature with excellent film-forming capability, and facilitated ion transport mechanism when complexed with all kinds of alkali metal salts.…”
