| As a new material, graphene has become a research hotspot in many industrial application fields due to its superior chemical stability, excellent electrical conductivity, enhanced resin adhesion and no secondary pollution as well as other comprehensive properties at coating-plating. Firstly, the development history of graphene dispersion in recent years was briefly summarized. The dispersion methods were mainly physical and chemical dispersion methods. The disadvantages of the two methods were analyzed and discussed and both methods more or less introduced defects and structural damage in the dispersion process. Secondly, two anticorrosive mechanisms of graphene were outlined. Firstly, the sheet structure of graphene was stacked to form a lethal physical barrier layer. Secondly, the good electrical conductivity of graphene provided a good conductive circulation path for the coating, endowing the coating with a good electrochemical protection performance. Then, the application of graphene in the field of thin-film anticorrosive and anticorrosion coating of water-borne organic functional filler was introduced in detail. The advantages and disadvantages of all kinds of composite coating preparation method were compared and improving strategies were put forward. Through analysis, graphene could enhance the organic coating adhesion and improve the physical shielding, mechanics and anti-corrosion performance or organic coatings. In addition, the application of graphene as a reinforcing phase in the coating of metal powder was introduced. The graphene composite coating of metal powder was deposited on the surface of the substrate by electrodeposition and chemical deposition. The graphene in the composite coating had excellent chemical stability and inhibited the corrosion rate of the coating. Finally, based on the above mentioned graphene's role in coating-plating and mechanical plating process, the research concept of "graphene-zinc" was put forward, and the development trend and research suggestions of graphene in the field of anticorrosive materials were put forward from the directions of dispersion stability, green, environmental protection, low cost, wider application range and industrial standardization. |
