Electrically conducting poly(para-phenylene sulfide) prepared by doping with nitrosyl salts from solution

Abstract

Para(polyphenylene sulfide) may be doped spontaneously and rapidly with nitrosyl salts (NOPF₆, NOSbF₆) from solution to yield an electrically conducting material (10^-1ohm^-1cm^-1). The level of conductivity is primarily dependent on the extent of dopant incorporation, which in turn is determined by the polymer’s crystallinity; the more amorphous the polymer, the more dopant it takes up and the more conductive it becomes. The incorporation of dopants produces irreversible chemical changes in the polymer resulting in the deterioration of its mechanical properties.
