CONDUCTING POLYMER COMPOSITES OF POLYPYRROLE AND A POLY(ARYLENE ETHERKETONE)

Electrically conducting composites of polypyrrole and a poly(arylene e ther ketone) were synthesized by electroinitiated polymerization of py rrole on a poly(arylene ether ketone)-coated platinum electrode. The e lectrolysis medium was water and p-toluene sulfonic acid. The conducti vities of the composites were in the range 1-10 S/cm. The composites w ere characterized by scanning electron microscopy, Fourier transform i nfrared, and thermal analyses. The composites were found to be compose d of bilayers which can be peeled into two free-standing polymer films . The solution side of the polypyrrole layer of the alloy film contain s globular structures, whereas the other side is smoother.
