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
## Abstract Composites of PUR and IL were prepared and specific conductivities and Shore A hardness were determined. IL were based on 1βalkylβ3βmethylimidazolium salts with counterions BF, PF, triflate, or ethylsulfate. Presence of IL increased the conductivity by five orders of magnitude. Variatio
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.
