Abstract
We report on our de conductivity measurements of mixed samples of poly aniline in the conducting form blended with polyaniline in the insulat ing form and made conducting subsequent to processing. Emeraldine base polyaniline (PANEB) dissolved in N-methylpyrrolidinone (NMP) and emer aldine base polyaniline doped with camphor sulfonic acid (CSA) but dis solved in NMP [and also in dimethyl sulfoxide (DMSO)] were mixed in va rious ratios according to the symbolic notation (PANCSA-NMP)(1-x)(PANE B-NMP)(x) and (PANCSA-DMSO)(1-x)(PANEB-NMP)(x), respectively. Films ob tained were then equilibrated in 1 M HCl for a period of 40-60 h and v acuum dried overnight prior to performing conductivity measurements. I t is shown that the room temperature conductivity increases with incre asing values of x. (C) 1996 American Institute of Physics.
