Study of the Effect of Mineral Schungite Dispersion on a Complex of Properties of Elastomer Materials Based on the SKTN­A – Kornev Yu.V., Chirkunova S.V., Boiko O.V., Simonova M. A., Shugaeva V. O., Yanovsky Yu.G. (P. 10).

Properties of the elastomer composites based on low­molecular siloxane rubber SKTN­A and filled with nanoparticles of mineral schungite obtained by an original technique are presented. The considerable increase in strength, tear resistance, hardness, relative hysteresis and specific deformation work (deformation energy) of the composites filled with nanodispersed schungite in comparison with composites filled with microparticles is shown. Nanoidentation of specimen of fillers of different dispersion is also done.

Key words: polymer nanocomposites, nanoparticles, schungite, nanoindentation, SKTN­A, mechanical properties
