▎ 摘 要
NOVELTY - A graphene-composite functional material comprises sulfonated graphene-grafted poly-3,4-(ethylene dioxythiophene) (I). USE - Graphene-composite functional material is used for preparing piezoresistive material, antistatic material and electromagnetic shielding material (claimed). ADVANTAGE - The graphene-composite functional material provides piezoresistive material having excellent piezoresistive property, threshold value of 0.5 Wt%, and high sensitivity, and is prepared by a simple process. DETAILED DESCRIPTION - A graphene-composite functional material comprises sulfonated graphene-grafted poly-3,4-(ethylene dioxythiophene) of formula (I). n=degree of polymerization, which is equal to 100-8000. An INDEPENDENT CLAIM is included for preparation of graphene-composite functional material, which involves preparing 1-20 mg/ml sulfonated graphene solution by dissolving sulfonated graphene in water, adding poly-3,4-(ethylene dioxythiophene) and 5-30 wt.% sodium persulfate solution to sulfonated graphene solution, reacting, concentrating obtained slurry, and curing.
