Abstract
We report a conformal coating of thin electronic film using polyaniline (PANI), for which a highly bulk dopant, dinonylnaphthalenesulfonic acid (DNNSA), was used for synthesizing the electrically conductive polymer. Corresponding polymer was observed to show enhanced processability in organic solvents. Additional solution doping with m-cresol was found to be helpful for decreasing the surface resistance of the polymer film. The electrical resistance of corresponding films was observed to be 60.3 Ω/□ after post film doping processes were applied.
The polymer layer was coated on a flexible aramid paper (NOMEX®, DuPont) varying the coating conditions for finding a sweet spot. Resultant polymer coats on the conformal substrate were observed to show promising surface resistance (140 Ω/□) showing any disadvantage in the mechanical integrity.
