✦ Synopsis

Films of polyaniline (PANI) have been prepared using laser-assisted deposition (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 resistance has been measured by the four-probe method and decreases with increasing temperature.

The films exhibit better conductivity in the morphologically ordered state.
