▎ 摘　　要

NOVELTY - This new utility model is one based on a kind of manufacturing equipment of electric circuit and graphite. Comprising with precision injector, micro-nano fiber collecting board, control system, high pressure direct flow power source electro-spinning shower nozzle, micro-nano fiber, graphene, base plate, X-Y platform, graphene oxidation environment device. Base plate used for protecting circuit, graphene layer is deposited on upper base plate, used for manufacturing material is circle, near site electric spinning direct-writing process for the pattern of circuit formation, graphite alkene oxidation process used for separating out the circuit. This new utility model using graphite alkene with different bandwidth but is the conductive or semiconductor property, can form conductor or transistor at on the graphene layer, take graphite as receiving plate of electrostatic spinning, using a proximal site electric spinning direct technology can carry out micro-nano fiber pattern of controllable graphene in deposition, manufacturing the circuit, using not conductive and oxidation graphite, may not be micro-nanometer fiber for protecting the graphite alkene oxidation, thus separating out circuit.
