Photocurable electrolyte based on sulfonated poly(ether ether ketone) [PDF]

Solid State Ionics, 2011
Abstract Photocurable electrolytes were prepared by mixing proton-conductive polymer sulfonated poly(ether ether ketone) (SPEEK), cross-linking monomer divinyl sulfone (DVS), photoinitiator phenylbis(2,4,6-trimethylbenzoyl)phosphineoxide (PI), dimethylacetamide (DMA), and ethanol. To investigate the proton transport property, a series of photocurable
