Abstract
The development of new materials made from the combination between conjugated polymers and new dopants is the objective of various researches groups around the world. This work presented the synthesis and characterization of Polyaniline (PAni) doped with folic acid. The material was synthesized through oxidative polymerization of the previously prepared emulsion of aniline in different concentrations with adding of the folic acid. The materials were characterized by spectroscopic techniques (infrared and UV-Vis), thermogravimetric analysis and electrochemical impedance spectroscopy. The infrared results suggested the effective formation of the materials and the results of the UV-Vis corroborate with this hypothesis. The thermogravimetric curves showed an intermediate behavior of the resulting materials coming from the starting materials (folic acid and PANi). By measuring the conductivity could be affirmed that the material behaved as semiconductors.
