Electrochemical synthesis, characterization, and spectroelectrochemical evaluation of poly(para amino benzoic acid-co-4,4-diaminodiphenyl sulfone) film

A novel poly(para amino benzoic acid-co-4,4-diamino diphenyl sulfone), i.e., pABA-co-DDS, was synthesized by simple electro-polymerization processes. Its structural properties were characterized using Fourier transform infrared (FTIR) spectroscopy. The copolymer displayed different voltammetry behaviors by applying various DDS concentrations. Among all examined pABA:DDS ratios, the 1:1 ratio provided the most suitable copolymer film on the surface of the electrode. The solubility tests revealed that the copolymer is just soluble in warm dimethyl sulfoxide (DMSO). Its electroconductivity was obtained to be 9.02x10(-2)Scm(-1). In conclusion, the synthesized novel conductive copolymer is an environmentally friendly substance that can be used in many areas.
