Structure and Electrical Properties of Polyaniline–MAX Composites

Powder samples of composites based on the conducting polymer polyaniline and MAX phase, specifically Ti<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>AlC, with various filling degrees, were synthesized using the “in situ” chemical oxidative polymerization method. The structure and morphology of composites were analyzed using scanning electron microscopy, infrared spectroscopy, and Xray diffraction analysis. The influence of the Ti<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>AlC filler content on the electrical properties of polyaniline was investigated. The activation energy of conductivity was calculated for samples of various compositions. It was established that a 5% content of Ti<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>AlC has the most significant effect on the structure and electrical properties of polyaniline composites.
