Synergetic effect of fullerene and graphene oxide nanoparticles on mechanical characteristics of cross-linked polyurethanes under static and dynamic loading

Abstract

The effect of low concentration of fullerene, graphene oxide and their combinations at an 85/15 ratio as additives on structure and mechanical properties of cross-linked polyurethanes has been studied at static and dynamic loading. Structure of nanocomposites has been determined from X-ray analysis and scanning electron microscopy. It has been shown that the presence of carbon nanoparticles in a composite results in its lower strength under both static and shock-wave loads. The synergetic effect of carbon nanoparticles mixture is revealed to have 1.25 times higher Young's modulus as compared with native polymer.
