▎ 摘  要

NOVELTY - Manufacturing an electrical responsive graphene-polyvinylidene fluoride (PVDF) material involves preparing a mother solution via mixing PVDF and an organic solvent at a first temperature; preparing a graphene-PVDF slurry via adding and mixing multiple graphene powders into the mother solution at a second temperature; and forming an electrical responsive graphene-PVDF material directly via removing the organic solvent from the graphene-PVDF slurry. The electrical responsive graphene-PVDF material is formed. The electrical responsive graphene-PVDF material is directly formed without applying an additional voltage. USE - Method for manufacturing an electrical responsive graphene-PVDF material. ADVANTAGE - The electrical responsive graphene-PVDF material of the present invention can not only output electricity through an additional electrode structure, but also can output the charge generated by the piezoelectric effect by itself because its own electrical conductivity characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electrical responsive graphene-PVDF material, which includes a first electron conducting end and a second electron conducting end, and comprising a polymer carrier, including PVDF polymer and has multiple micro-pores; and multiple conductive micro-bodies, including graphene powder, the conductive micro-bodies are embedded in the polymer carrier and on at least potion of the surface of the micro-pores, and the conductive micro-bodies provide at least a first conductive path to the first electron conducting end and provide at least a second conductive path to the second electron conducting end, the electrical responsive graphene-PVDF material generates a charge changing after receiving a non-electrical energy input, and outputting multiple electrons via passes through at least one of the first conductive path and the second conductive path to at least one of the first electron conducting end and the second electron conducting end; where the weight percentage of the graphene powder of the conductive micro-bodies is not more than 50 wt.% relative to the PVDF polymer of the polymer carrier. DESCRIPTION OF DRAWING(S) - The drawing shows a method for manufacturing an electrical responsive graphene-PVDF material.
