| Popis: | We report on our dc conductivity measurements of mixed samples of polyaniline in the conducting form blended with polyaniline in the insulating form and made conducting subsequent to processing. Emeraldine base polyaniline (PANEB) dissolved in N‐methylpyrrolidinone (NMP) and emeraldine base polyaniline doped with camphor sulfonic acid (CSA) but dissolved in NMP [and also in dimethyl sulfoxide (DMSO)] were mixed in various ratios according to the symbolic notation (PANCSA‐NMP)1−x(PANEB‐NMP)x and (PANCSA‐DMSO)1−x(PANEB‐NMP)x, respectively. Films obtained were then equilibrated in 1 M HCl for a period of 40–60 h and vacuum dried overnight prior to performing conductivity measurements. It is shown that the room temperature conductivity increases with increasing values of x. |
