The research work is dedicated to influence of electromagnetic and hydrodynamic effect of explosion of the conductor on receiving and physical properties of polymeric nanocomposites. The purpose of work consists of: carrying out scientific researches which are directed on clarification of electromagnetic influence and hydrodynamic effect which arises during electric explosion of the conductor. Its influences on formation of structure, interphase interaction and properties of the received polymeric nanocomposites; development of the theory, on the basis of pilot studies which will allow to approach physical and chemical modification of polymers for the purpose of receiving the new metalpolymeric nanocomposites capable to work in extreme conditions; creation of competitive scientific works, scientific and scientifically applied results, introductions of innovative activity. Providing on this basis of conditions implementation of profound scientific and scientific and technical training of specialists, in branches of nanophysics and nanochemistry. Object of research - power exchange processes in the polymeric nanocomposites received on the basis of linear the flexible of polymers (PVC, PS, PMMA, PVB) which are modified by nanodisperse metals and external fields. The object of research consists in studying of influence of electromagnetic and hydrodynamic effect of explosion of the conductor in the mass of polymer on a complex of properties of the received polymeric nanocomposites. Methods of researches: a volume dilatometry, the differential thermal analysis, the thermogravimetric analysis of -calorimetry, IR-spectroscopy, US-defectoscopy, optical microscopy, an optical quantitative metallography, the chemical analysis, the X-ray diffraction analysis, DMA in the field of sound and ultrasonic frequencies, Raman Spectroscopy, a complex (ИТ- -400, ИТ-С-400) of measurement of thermophysics quantities ?-, ? - dosimetry. Influence of electromagnetic and hydrodynamic effect which arises during electric explosion of the conductor in the hydraulic environment with a mass of polymer, in particular, of processes of cavitation and electrodispersion on receiving nanodisperse metal fillers of the different physical and chemical nature of a surface, dispersion, phase topology, in a certain polymeric matrix is studied. It is established that for electric explosion of linear conductors from Cu, W, Mo, Fe, NiCr at given sizes and the corresponding initial tension time of receiving a nanodisperse filler, changes in sequence of Fe<Cu<NiCr<Mo<W. In case of hydrodynamic effect, thanks to processes of cavitation and electrodispersion, it is possible is directed to direct physicochemical properties of a surface of a filler and its dispersion. It is shown that in case of the nanodisperse metal of the same name activity of fillers can be regulated in wider limits by means of an electrochemical method dispergating. Existence of the active centers on a surface of a disperse phase allows to regulate a complex of properties of composites which are in temperature, electric, dynamic mechanical, radiation fields. The elaborated theory of anisotropy of thermophysics properties of heterogeneous polymeric systems, gives the chance to use composites as heat carriers, heat insulators, generators, sensors, acoustic lines of a delay, permanent magnets. Using of new model approaches and mathematical methods of their description allow to analyse a contribution of a diffusive and drift component of carriers of current to electrophysical properties of heterogeneous polymeric systems. Theoretical development in case of action on a composite by a temperature field at a constant and/or alternating voltage of the power supply and ?--radiation allows to receive, by modulation of current, new ways of generation of current in a chain. The found-out behavior of heterogeneous polymeric systems in fields of the different physical nature and power of indignations, in case of simultaneous operation of a composite in dynamic and temperature, temperature and radiation and/or electric fields.
