NOVELTY - Epoxy composition comprises amphiphilic block copolymer that includes epoxy miscible block and epoxy immiscible block, resin material and amine modified graphene oxide. USE - Epoxy composition. ADVANTAGE - The epoxy composition has improved toughness. DETAILED DESCRIPTION - Epoxy composition comprises amphiphilic block copolymer that includes epoxy miscible block and epoxy immiscible block, resin material and amine modified graphene oxide, where the epoxy composition shows a synergic effect in critical strain energy release rate (Glc) value versus predicted value calculated by adding the Glc value for neat resin material, plus the difference in Glc found when adding the amphiphilic block copolymer to the resin material versus the neat resin material, plus the difference in Glc found when adding the amine modified graphene oxide to the resin material versus the neat resin material. An INDEPENDENT CLAIM is included for a method for producing an epoxy composition, which involves: (A) dissolving an amphiphilic block copolymer in a solvent to produce an amphiphilic block copolymer solution; (B) adding amine-modified graphene oxide to the amphiphilic block copolymer solution to produce a graphene oxide containing mixture; (C) mixing a resin component into graphene oxide containing mixture to produce a resin containing mixture; and (D) removing the solvent from the resin containing mixture to produce a solvent-free mixture.
