NOVELTY - Graphene-silica composite material comprises 0.1-99.9 wt.% graphene and 0.1-99.9 wt.% silica. USE - Graphene-silica composite material used as reinforcing filler in silicone polymer. ADVANTAGE - The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-silica composite material comprising dissolving graphene in greater than or equal to 0.001 mg/ml solvent to obtain suspension, carrying out ultrasonic dispersion, adding aqueous silicon precursor where molar ratio of water to silicon precursor is 4:1, adjusting pH value to 7, stirring, settling, filtering or separating by vacuum distillation, washing to remove unreacted raw materials, impurities or by-products and drying.
