Unique morphologies have been found when pyrrole and 3-methylthiophene were electrochemically polymerized on two porous substrates, [open quotes]Nuclepore[close quotes] and stainless steel mesh. Polypyrrole formed highly oriented tubular fibrils on Nuclepore with striations along the direction of growth having conductivities between 2000 and 3000 S cm[sup [minus]1], higher than those observed in typical preparations of polypyrrole films. On the other hand, poly(3-methylthiophene) formed braided and spiralled fibrils. With the electrodes arranged horizontally, spiralled poly(3-methylthiophene) possessed temperatures independent conductivities.
