Publication number: 20110017955Abstract: The present invention provides a modified curing agent for a thermosetting resin, such as epoxy resin. As one example, the epoxy curing agent comprises: (a) multiple nano graphene platelets; (b) a chemical functional group having multiple ends with a first end being bonded to a nano graphene platelet and at least a second end reactive with the epoxy resin; and (c) reactive molecules acting as a primary cross-linking agent for the epoxy resin; wherein the nano graphene platelet content is no less than 0.01% by weight based on the total weight of the modified curing agent. A modified curing agent containing reactive molecule-functionalized NGPs enable excellent dispersion of NGP in a resin matrix and the resulting nanocomposites exhibit much better properties than those of corresponding nanocomposites prepared by directly mixing dried NGPs with the thermosetting resins.Type: ApplicationFiled: July 23, 2009Publication date: January 27, 2011Inventors: Aruna Zhamu, Bor Z.
