Description

technical field [0001] The invention relates to a modified graphene epoxy acrylate resin and a preparation method thereof, belonging to the technical field of resin preparation. Background technique [0002] Graphene is one of the materials with the highest strength known, and it also has good toughness and can be bent. The theoretical Young's modulus of graphene reaches 1.0TPa, and its inherent tensile strength is 130GPa. The reduced graphene modified by hydrogen plasma also has very good strength, and the average modulus can be greater than 0.25TPa. Graphite paper composed of graphene flakes has many pores, so graphite paper is very brittle. However, functionalized graphene obtained through oxidation, and then graphite paper made from functionalized graphene will be extremely strong and tough. At the same time, graphene has applications in many fields such as sensors, flexible screens, photosensitive elements, and composite materials due to its good stability and photoele...
