Notes:
Obtaining a “hybrid” electroconductive polymer composite material on the basis of a fibrous carrier and polypyrrole (pPy) was studied. As fibrous carriers, polyacrylonitrile (PAN) and chemically modified polyacrylonitrile possessing ion-exchange properties were used. FeCl3, chosen as an initiator for oxidative polymerization of pyrrole (Py), was introduced in the fibrous matrix by sorption from an aqueous or diethylether solution. The polypyrrole film was deposited onto/in a matrix prepared in this way by polymerization of pyrrole in a vapor phase, from the vacuum, or from a solution of Py in toluene. In some cases, an additional doping of the obtained (electroconductive) pPy film, with iodine vapors in the vacuum, was also applied. An electroconductive composite material, with volume resistivity of about 10 Ω cm, was obtained. The results, related to the different nature of the fibrous carrier and different procedures for the oxidizer introduction or pPy deposition, were discussed. © 1996 John Wiley & Sons, Inc.
