▎ 摘　　要

NOVELTY - The material (1) has a substrate (10), and a graphene oxide (20) which accounts for 5-60 wt. % based on a total weight of the substrate and the graphene oxide. The substrate has an oxidized, doped, or undoped carbon nanotube, a doped or undoped graphite, a doped or undoped graphene, a molybdenum dioxide, or a combination, and a doping element has sulfur, phosphorus, boron, nitrogen or a combination. The graphene oxide includes a graphene oxide having a one-dimensional conducting direction, a graphene oxide having a two-dimensional conducting direction, or a combination. USE - Composite carbon material used for current flexible electronic components or wearable electronic components. ADVANTAGE - Achieves the unexpected effects by mixing the substrate and the graphene oxide in a specific proportion enables the mixed and/or entangled composite carbon material to have excellent hydrophilic property, flexibility, electrical conductivity and dispersity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of preparing a composite carbon material. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of a composite carbon material. Material (1) Substrate (10) Graphene oxide (20)
