A series of acidic ionic liquid (ILs) based on imidazole and pyridine were synthesized and fully characterized by using FTIR, ¹H and ¹³C NMR techniques. The acidic ILs applied as solvent and dopant for polymerization of 3-aminobenzoic acid (3ABA) by using of ammonium persulfate as an initiator. The synthesized P3ABAs-acidic ILs were characterized by FTIR, XRD, SEM, UV-Visible and TG-DTG analysis. The electrical conductivity of P3ABAs samples was measured by four probe method. The P3ABA-[PyCAA][HSO4] (0.30 S/cm) exhibited a higher electrical conductivity than that of the P3ABA-[HPy]HSO4] (0.28 S/cm), P3ABA-[IMBS][Cl] (0.22 S/cm) and bare P3ABA (0.20 S/cm). Based on the SEM micrographs, the acidic ILs changed the morphology of the P3ABA from being completely granular. The XRD patterns of the P3ABAs-acidic ILs samples displayed a more crystalline nature than that of bare P3ABA. The solubility and viscosity of P3ABAs-acidic ILs in polar organic solvents were greater than in bare P3ABA. Moreover, absorption (UV-vis) properties of the synthesized P3ABAs in the presence and absence of acidic ILs were examined. Based on TG-DTG curves, the thermal stability of the P3ABAs-acidic ILs was improved relative to bare P3ABA. The results showed that acidic ILs species form soft templates which assembled 3ABA molecules into specific nanostructures.
