The development of new branches of science and technology, in particular, organic or "plastic" electronics, sensor devices, flexible energy converters, antistatic coatings arise interest in composite polymer materials with conducting polymer fillers [1]. Conductive composites based on conjugated polyarenes and elastic polymer matrices are representatives of a new type of composite materials, in which, unlike traditional metal fillers, conjugated polymers with their own electron conductivity are used.
In the present research, the main features of synthesis, structure and charge transport in nanocomposites based on conducting polymers (polyaniline and poly-o-toluidine) fabricated in the matrix of polystyrene were studied [2]. The influence of nature and concentration of polymer nanofiller on the morphology of film samples and the structure of composites were investigated by X-ray phase analysis, FTIR spectroscopy, SEM and optical microscopy. It has been established that polyaniline can be fabricated in the form of a 1D nanostructure as a conductive polymer mesh, while poly-o-toluidine forms of nanocrystalline in the middle of polystyrene matrix. According to the data of FTIR spectroscopy, when composites forming the conducting fillers are set in the form of a salt of emeraldine, which makes it possible to improve the performance of the composites and the ability their application as anti-static and anti-radar coatings.
