Correlations between morphology and conductivity properties of films of polyaniline

Films of polyaniline (PANI) have been prepared using laser-assisted deposit ion (LAD), The morphology of these films has been examined using low-angle X-ray diffraction, scanning electron microscopy and atomic force microscopy , The films exhibit dense packing and better ordering of polymer strands as compared with films prepared using electrochemical deposition, The sheet r esistance has been measured by the four-probe method and decreases with inc reasing temperature. The films exhibit better conductivity in the morpholog ically ordered state, Copyright (C) 2000 John Wiley & Sons, Ltd.
