## Abstract Hybrid solid polymer electrolyte films consisting of poly(vinyl alcohol) (PVA), poly(methyl methacrylate) (PMMA), LiBF~4~, and ethylene carbonate/propylene carbonate (EC/PC) were prepared with a solventβcasting technique. The complexation was investigated with Fourier transform infrared
The free volume behaviour of the polyacrylonitrile/lithium triflate system is investigated over the composition range 0 -75 wt % salt. The addition of salt, up to 45 wt %, to the PAN polymer substantially increases the free volume as measured by the orthopositronium pickoff lifetime, 3 . Beyond this
