Abstract
Supramolecular structures (domains, associates, nanoparticles) based on conjugated polymers are attractive basis for creating new materials for use in modern electronics. In this work we propose a mechanochemical method of synthesis of electrochemically active aniline- and N-(2-hydroxyethyl)aniline-based polymers. The effect of hydroxyethyl moieties on self-assembly of nanoparticles has been studied. Methods of dynamic light scattering and transmission electron microscopy have shown formation of nanosized particles of polyaniline and submicron particles of poly[(N-2-hydroxyethyl)aniline]. The electrical properties of materials were investigated: conductivity of polyaniline is 0.14 Sm/cm, which is constant over a wide range of temperatures and frequencies; conductivity of poly[(N-2-hydroxyethyl)aniline] is in range 2 × 10–9–1 × 10–6 Sm/cm, which strongly depends on temperature and alternating current frequency.
