▎ 摘　　要

NOVELTY - Preparing graphene oxide based functional composite material involves immersing composite paper in the graphene oxide dispersion, and then keeping the obtained dispersion solution for 3-5 hours to obtain modified composite paper particles. The modified composite paper particles are gently removed from the dispersion solution using tweezers, and then spread on an aluminum foil. The modified composite paper particles spread on the aluminum foil, are then heated at 40-60 degrees C for 10-12 hours to obtain graphene oxide based functional composite material as the product. USE - Method for preparing graphene oxide based functional composite material (claimed). ADVANTAGE - The method enables to prepare graphene oxide based functional composite material of uniform thickness in a simple, cost-effective and environmental-friendly manner. The prepared graphene oxide based functional composite material has good stability and good absorption properties, and thus has wide application prospects.
