Abstract: The present invention discloses a nanocomposite coating composition and coating method for antenna reflector. The nanocomposite coating composition comprises a polymer matrix resin and a plurality of graphene nanoparticles. A portion of hardener is firstly added into epoxy resin system. The plurality of graphene nanoparticles is added to acetone solvent and dispersed using an ultrasonic disperser. An appropriate amount of prepared epoxy resin is added to the mixture of graphene and acetone solvent and stirred using a mechanical stirrer for certain period. The sonication process is applied to the graphene incorporated resin mixture for a duration of about 30-120 minutes. The acetone in the mixture is removed using a magnetic stirrer and a vacuum oven. Further, the remainder of the hardener is added to the mixture and degassed using vacuum oven to form the nanocomposite coating composition.
