▎ 摘　　要

NOVELTY - The composite material has a substrate containing molybdenum carbide. A graphene layer is coated on the surface of the substrate. A graphene structure extends from the graphene layer and is provided with a coral structure. The surface of the substrate has irregularities. The area ratio of the graphene structure per unit area of the surface of the substrate is 20% to 80%, on a projection image looking down from the top of the composite material. The graphene structure is grown on the surface of the graphene layer. The composite material has a water contact angle of 90 degrees or more. USE - Composite material for flexible electrode used in various electrochemical device fields such as capacitors, batteries, and sensors. ADVANTAGE - The material for flexible electrode exhibits excellent water repellency and maintains excellent electrical properties even when exposed to extreme environments such as high temperature, high humidity, and water for long time. The material for flexible electrodes maintains excellent electrical properties even in repeated bending. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing composite material for flexible electrodes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram illustrating the manufacturing method of composite material for flexible electrodes.
