Quantum-chemical modeling, synthesis and properties of electrically conductive materials based on polyaniline

Quantum-chemical modeling of the polyaniline (PANI) molecule was performed. Methods for synthesizing PANI via oxidative polymerization were developed, and the morphology and physicochemical properties were comprehensively studied and optimized. Polymer-composite materials consisting of PANI and carbon-based materials within a PLA matrix were formed. According to cyclic voltammetry and impedance spectroscopy, these composites exhibit conductivities ranging from 0.10 to 25 S/cm, making them promising for use in various sensor devices in microand nanoelectronics, biomedicine, as well as in the development of anti-corrosion and antistatic coatings.
