Abstract
The structure and mechanical properties of polymer-nanodiamond composites based on block-copolymer polystyrene-polybutadiene-polystyrene have been studied. It is revealed that, if either the nanodiamonds produced by detonation synthesis or the nanodiamond soot are introduced into block-copolymer thermoelastoplastic, the mechanical performances of the modified polymer matrix change significantly. It is shown that the optimal content (according to the modifying effect) of the nanodiamond soot in polymer composite is about 8–10% by weight. It is found that the spatial distribution of nanodiamond particles in the polymeric matrix of thermoelastoplastic is determinative in modifying the properties of polymeric nanocomposite. Ways to use the examined polymer-nanodiamond composites are discussed. The obtained results are important for the technological development of modified large-scale polymers, high-strength adhesives, glues and molten adhesives, and impact-resistant plastics.
