Throughout the evolution of humanity, polymers have always been present in the composition of the most varied types of materials that are used daily in various activities of human daily life. With that, there was a need for new studies involving polymers and, mainly, conductive polymers that are increasingly intensified in the scientific world. Polyaniline, which is a conductive polymer obtained through the polymerization of aniline, has gained prominence, since its synthesis is easy to carry out and economically viable. In this work, the main objective was to synthesize the aniline monomer through the chemical method using iron III chloride and basalt powder as oxidative agents and doping agents in the reaction, respectively. Fourteen experiments were carried out, varying temperature (0 and 25), reaction time (1h and 4h) and addition of basalt powder. The samples were characterized by Gravimetric Analysis, Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). From the Gravimetric Analysis it was possible to detect which samples were taken for analysis according to the yield of each one, by the FTIR it was possible to determine the characteristics of the materials present in the samples through the stretches present in the analysis. From the TGA and DSC analyses, the behavior of the material was observed through its thermal resistance, being possible to verify that the samples that have the basalt powder suffered less degradation than the samples that did not contain the powder in its structure. Therefore, with the characterizations carried out, polyaniline oxidized with iron III chloride and codoped with basalt powder was obtained with potential for a thermal insulator |
