Synthesis of Polyaniline/Scarlet 3R as a Conductive Polymer
Polyaniline (PANI) was prepared in the presence of the acidic dye scarlet 3R. Color tuning was performed on PANI through doping–dedoping processes and by changing the solvent used during the optical absorption spectroscopic measurements. The chemical structure of the resulting polymer–dye composite was analyzed using infrared absorption spectroscopy, and it showed the occurrence of secondary doping in m-cresol. The shape of the UV–Vis optical absorption spectra for the composite solution isdoi:10.3390/polym12030579 pmid:32150876 fatcat:ydxhs4j3pzgntobonirzplloly
