G. Koshechko, O. Yu. Posudievsky, Ya. I. Kurys, and V. D. Pokhodenko Results are summarized for studies on the development of hybrid nanocomposite materials based on organic conjugated conducting polymers (CP) such as polyaniline, polypyrrole, and polythiophene as well as studies of the structure, physicochemical, and functional characteristics of these materials. Such nanocomposites have been shown to display new functional properties due to the interaction of their components. These materials hold promise for use in various areas (chemical power sources, optoelectronics, and electrocatalysis) for creation of advanced devices. Significant attention is given to nanocomposites based on CP and various 2D materials prepared by mechanochemical and electrochemical methods. Key words: organic conducting polymers, hybrid nanocomposites, 2D materials, physicochemical properties, functional characteristics. The chemistry of organic conducting polymers (CP) has attracted considerable attention from the moment of their discovery due to the unique set of properties of these materials including electrical conduction, redox activity, and luminescence [1]. In recent years, there has been intensive work on the development of nanostructural materials since they often demonstrate characteristics not achievable for bulk or even microstructural analogs. Nanostructured CP may be obtained as dispersions or powders consisting of nanoparticles or nanoparticle aggregates as well as composite nanomaterials [2-4]. In the latter case, organic–inorganic hybrid nanocomposites (HNC) are obtained using various inorganic compounds. These nanocomposites hold interest in light of their novelty and possible practical applications. Synergism of the properties of the organic and inorganic components is possible in such HNC due to their interaction and the electronic nature of the CP. This may lead to achieving optical, electrical, and photoluminescence characteristics, ion transport, energy transfer, electrochemical activity, and sensor response selectivity, which hold promise for practical application [2-11]. The studies on nanostructured CP and derived HNC reported in the literature have been devoted to nanomaterials often prepared by the traditional sol–gel method [2-11]. The results of these studies show that these nanocomposites may have new functional properties. However, their stability and methods for their manufacturability are still inadequate. In the present work, we briefly present the most important results of our studies of both new and more efficient methods for the preparation of HNC, in particular, using the mechanochemical method, as well as studies of the structure, physicochemical, and functional characteristics of the resultant original nanomaterials [12-34]. 0040-5760/17/5305-0285 ©2017 Springer Science+Business Media New York 285 ___________________________________________________________________________________________________ L.
