One of highly conductive polyaniline emeraldine salt (PANI-ES) has a disadvantage of difficulty in processing due to its poor solubility. Therefore, we conducted improving above disadvantages by dedoping them using a base solution to form a polyaniline Emeraldine Base (PANI-EB) and Leucomeraldine Base (PANI-LB) states. According to used reduction agent, PANI-ES is dedoped to emeraldine base (EB) using NH3OH and leucoemeraldine base (LB) states using hydrazine monohydrate. This PANI-EB and LB form compensated for the problem of processing, which is a disadvantage of the existing PANI-ES, and fabricated film through a solution process that cannot be performed in PANI-ES. Therefore, PANI-EB and LB films were doped using HCl and analyzed its optical properties and electrical properties with absorption spectra, electrical conductivity and hall effect measurements. As a result, we confirmed the optimized condition as re-doped PANI-LB at improved processability and conductivity with 56 S/cm. |
