摘要：
Graphene fillers are shown to be remarkably effective in suppressing crack propagation in epoxy polymers. The graphene fillers show comparable increases in fracture toughness and fatigue crack propagation resistance to carbon nanotube, nanoparticle, and nanoclay additives at one to two orders of magnitude lower nanofiller weight fraction. This extraordinary property is related to deflection processes associated with the high-aspect-ratio sheet structure of graphene.© 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
