A STUDY OF ORDERING OF GRAPHENE-GRAPHANE METAL-CONTAINING COMPOSITES SYNTHESIZED AT DIFFERENT TECHNOLOGICAL PARAMETERS

Keywords: metalloligomers; oligophenolates of vanadium, iron, copper; оptimization of the polymerization process; graphene-graphane structures

Abstract

The conditions and features of the graphene-graphane structures formation during the preparation of metal-polymers with the aim of the directed creation of their structure have been studied. It was found for the first time that the use of metal clusters with a three times narrower size range of 1–10 nm makes it possible to increase the content of graphene-graphane structures in metal polymers by 2–2.5 times. The obtained oligomers have promising characteristics for use as heat-resistant polymer binders for the manufacture of high-strength composites reinforced with carbon fibers and fabrics.
