Abstract: A method of producing functionalized graphene oxide includes mixing graphene oxide with a reactive monomer containing at least one epoxy functional group and a secondary functional group that is selected from vinyl, acrylate, methacrylate, and epoxy to form a mixture, adding an activation agent, heating and stirring the mixture, cooling the mixture, separating the particles from the mixture, and drying the particles to produce functionalized graphene oxide. A method of manufacturing a cured polymer resin using functionalized graphene oxide includes mixing functionalized graphene oxide with a resin precursor to produce a functionalized graphene mixture, wherein the particles contain functional groups nearly identical to, or identical to, a polymer precursor material, adding a curing initiator to the functionalized graphene mixture and mixing to produce a formulation, depositing the formulation into a desired shape, and curing the formulation to form a polymer having functionalized graphene oxide groups in a base polymer material.

Abstract: An acrylic adhesive composition includes a first part including an aminoborane initiator and acrylate or/and methacrylate monomers, and a second part including inert microcapsules of a cure activator and acrylate monomers, wherein the microcapsules are breakable, such that when broken, the first part reacts with the second part and the acrylic adhesive begins to cure. A two-part structural adhesive includes a suspension component containing an aminoborane initiator, and microcapsules containing an encapsulated component, wherein the microcapsules are dispersed in the suspension component. A method of activating an aminoborane initiator suspension to form a structural adhesive includes adding microcapsules containing an encapsulated component, to the aminoborane initiator suspension at a predetermined ratio, and breaking the microcapsules to activate curing.
