Description
Summary:Polyaniline has attracted increasing attention due to its various excellent properties; however, polyaniline doped by the acids with small molecules has poor solubility and thus impeded its widespread application. In this paper, soluble and conductive polyaniline doped by itaconic acid was prepared and orthogonal experiment design was conducted to study the impact of the synthesis parameters on the productivity and conductivity of polyaniline. The result showed that the oxidant-aniline molar ratio is the most prominent factor influencing the comprehensive index. The optimum oxidant-aniline molar ratio, oxidant concentration, itaconic acid-aniline molar ratio and itaconic acid concentration values were found to be 1.5, 0.5 mol/L, 0.5 and 0.5 mol/L, respectively. The chemical structures of the products based on the FT-IR spectra confirmed that the different oxidant states and molecular connection modes of polyaniline backbones brought about the conductivity diversity. The UV-Vis spectra showed that the protonation occurred at the imine segment of the polymer chain and polyaniline was fully doped with the itaconic acid. The itaconic acid doped polyaniline prepared under the optimal condition has high productivity, conductivity of 2.11×10 −2 S/cm and good solubility in the organic solvents.
