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

A conducting polymer composite was prepared by the postpolymerization of pyrrole in a polyacrylonitrile (PAN) matrix film. To enhance the electrostatic interaction between the two phases, a small amount of a sulfonate (SO 3 Οͺ ) or a carboxylate (COO Οͺ ) group was incorporated into the PAN structure.
Iodine diffusion in ion-modified polyethylene (PE) using the Rutherford Backscattering method (RBS) has been studied. P E was irradiated by N+, Ar+ and As+ ions with an energy of 150 keV and doses of 1 X 1013-1 X 1015 cm12. Iodine diffused in ion-modified PE from vapor at 9OoC. Iodine's concentratio
Several polymer electrolytes have been obtained, based on binary blends of polyethylene oxide (PEO), polypropylene oxide, and polyphosphazene by means of solvation with lithium triflate. The different samples were studied both as to their microstructure and for their electrical properties, either th
