▎ 摘　　要

NOVELTY - Producing graphene composite material by using plant comprises placing the plant seedling into graphene nutrient solution, weighing, placing into electric field, and recording the weight number and test date; injecting nutrient solution with known graphene content in the container with known capacity, measuring the resistance value of the nutrient solution and recording the test date and resistance value; using soilless culture method or soil cultivation method to cultivate the nutrient solution containing graphene plant; and using the conductivity of the graphene. USE - The method is useful for producing graphene composite material by using plant. ADVANTAGE - The method enables producing the graphene composite material with excellent characteristics.
