(GPE), using polyvinylidene fluoride‐co‐hexafluoropropylene (PVdF‐HFP) and cross‐linked
poly (ethylene oxide)(PEO), with an ionic liquid and salt (LiTFSI) mixture. The polymers
resulted in a semi‐interpenetrated polymer network (semi‐IPN), hosting an ionic liquid
(IL)/salt mixture, and thus exhibited high ionic conductivity and excellent mechanical
properties. Nuclear magnetic resonance (NMR) diffusion measurements and relaxation …
