▎ 摘 要
NOVELTY - An exterior is obtained by spreading graphene solution obtained by manufacturing mixture of graphene, water and ethanol, adding and diffusing a surfactant into mixture on surfaces of exterior product, evaporating and coating graphene solution on surface of exterior product. USE - Exterior product e.g. machine, mold, cutter, motor, exterior component of vehicle, exterior component of ship, medical instrument, tool, helmet, weapon, frying pan, pot and guardrail of road. ADVANTAGE - The exterior product has excellent friction resistance and impact resistance.
