▎ 摘  要

NOVELTY - The method involves using an ionic liquid as a plating solution. A graphene oxide is dispersed in the ionic liquid. The ionic liquid is made of metal ions. The graphene-metal composite coatings are deposited on the cathode substrate by current control pulses. The current control pulse is provided with a forward pulse period and a reverse pulse period. The graphene is deposited on a cathode substrate by a voltage-controlled pulse. The voltage control pulse is provided with a positive pulse period when the voltage and current are negative on the deposition surface, and a negative pulse period when the voltage and current are positive on the deposition surface. The ionic liquid is a choline chloride and ethylene glycol system. The metal ions are copper ions, chromium ions, gallium ions, indium ions, iron ions, nickel ions, silver ions, platinum ions, or gold ions. USE - Method for electroplating graphene-metal composite coating using complex pulse. ADVANTAGE - The method is simple, lower in cost, and has no environmental pollution caused by electroplating. The method can be applied to large-area coating or film production. The graphene-containing conductive wire is printed on the PCB to make a brushless motor stator, and thus providing a new type of motor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a printed circuit board. DESCRIPTION OF DRAWING(S) - The drawing shows a Raman spectrum diagram of the graphene-metal composite coating.
