Aniline monomer was distilled once prior to use for the polymerization reaction. Then, solid/liquid interfacial polymerization reaction was conducted with a reaction mixture with 1:2-2.5 aniline:CSA ratio, 4:1 aniline to ground APS, at 25°C; the reaction was carried for 24-48 hrs to ensure polymerization had concluded. The resulting reaction mixture was filtered via aqueous funnel extraction twice. Then, the solvent was evaporated using a rotary evaporator. Any residual water was manually removed from the solid, then an acetone wash was conducted. The resulting powder was dried at 60°C for 24 hrs under reduced pressure. The resulting emeraldine salt (ES) powder was dedoped using a 0.1M NH3 solution, stirred for 24hrs. The resulting emeraldine base (EB) powder was washed thrice with water, acetone, and chloroform, then dried at 60C for 24hrs under reduced pressure. Finally, ES was reformed by mixing the EB and CSA(+) powder in a 1:0.5 molar ratio with a mortar-and-pestle.
