▎ 摘  要

NOVELTY - Obtaining conductive composite material involves mixing 10-40 wt.% expanded graphite or graphene, 30-50 wt.% resin (thickener, rheological agent or polyelectrolyte and/or hydrocolloid) and solvent to complete 100% (essential oil, water or alcohols), calendering the obtained paste on a paper, metallic film or polymeric film, drying the oven at 60-100 degrees C to evaporate excess solvent for 3 hours, cooling down, calendering the paste cooled at a variable temperature between 60-200 degrees C, pressing the cooled paste at a variable temperature between 60-200 degrees C to obtain from the conductive composite material. USE - Method for obtaining conductive composite material used in heated insoles, body heating systems, electrodes, miniaturized heaters, sensors, absorbers or heat sinks, cosmetic devices, medical devices, fluid joints, vibration dampening, electrochemical electrodes, fuel cell components, components battery, solar cell, thermal interface materials, nano transistors, static charge sinks, lubricating agent and surface protective agent.
