Abstract

The effect of modifying detonation nanodiamond additives on the stress-strain properties of polymer nanocomposites is investigated using polysiloxane polyblock copolymers as an example. It is shown that the formation of a physical network of supramolecular structures (due to self-organization initiated by force fields of highly active nanoparticles) can lead to an increase in the physicomechanical parameters in the range of small strains (up to 100%) without changing the chain microstructure. The use of composites involving fillers of the H type (with a high surface activity) and the L type (with a low surface activity) provides a maximum efficiency of interaction of the force fields induced by supramolecular structural units. The force interaction results in a more “efficient” supramolecular organization of the polymer and ensures a synergetic increase in the physicomechanical parameters with the use of L-Hfillers.
