中文摘要:
      石墨烯作为新型材料,具有优异的化学稳定性、极好的导电性及可增强树脂附着力和无二次污染等综合性能,成为诸多工业应用领域的研究热点。首先,简要概述了近年来石墨烯分散性的发展历程,分散方法主要以物理和化学分散法为主,并对两种方法的弊端进行了分析和讨论,得出两种方法在分散过程中都会引入缺陷及结构受损。其次,概述了石墨烯的两种防腐机理,第一种机理是石墨烯片状结构堆叠形成致密物理阻隔层,第二种机理是依靠石墨烯良好的导电性,给涂镀层提供良好的导电循环通路,赋予涂镀层良好的电化学保护性能。然后,对石墨烯在薄膜防腐领域和水性有机防腐涂料功能化填料应用等方面进行了详细介绍,比较了各类复合涂料制备方法的优缺点并提出了改进策略,分析得到了石墨烯增强有机涂料附着力的同时,还提升了有机涂料的物理屏蔽性能、力学性能和防腐性能。另外,介绍了石墨烯作为增强相在金属微粉镀层中的应用,通过电沉积和化学沉积法,在基体表面沉积石墨烯金属微粉复合镀层,复合镀层中的石墨烯具有极好的化学稳定性,抑制了镀层的腐蚀速率。最后,基于上述石墨烯在涂镀层中的作用及机械镀工艺,提出了“石墨烯-锌”的研究概念,并从分散稳定性、环保性、经济性、适用范围、产业标准化等方向,提出了石墨烯在防腐材料领域里的发展趋势及研究建议。
英文摘要:
      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.
