NOVELTY - A polymer composite is doped with graphene oxide. USE - Polymer composite. ADVANTAGE - The polymer composite has adjustable dielectric constant, low density, and excellent mechanical performance and bonding force with respect to graphene oxide and resin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polymer composite, which involves mixing and dispersing graphene oxide in a solvent, ultrasonically treating for 1-3 hours to obtain a graphene oxide suspension, adding solvent preheated to 65-100 degrees C, ultrasonically processing for 1-2 hours, heating to 25-100 degrees C, decompressing, stirring and evaporating the solvent, placing in a vacuum drying environment, defoaming for 2 hours at 80 degrees C, removing residual solvent, adding preheated curing agent, stirring, casting in a mold, placing in a vacuum environment, defoaming, curing, cooling to room temperature, and demolding.
