Conteúdo: |
Flexible and free-stantding films from blends of polyurethane, based on castor oil, and polyaniline were obtained with various compositions by casting. Significant increase on conductivity followed by a considerable decrease on doping time was obtained by doping the films in N, N-dimethylformamide (DMF) solution with p-toluene sulphonic acid (TSA) or HCl instead of the conventional doping aqueous solution. This doping efficiency is proposed to be due to an improved swelling of the blend structure caused by the solvent. |
