摘　　要：为解决石墨烯在涂层中的分散问题,先以空心玻璃微球(HGM)和氧化石墨烯(GO)为原料,制备了氧化石墨烯包覆空心玻璃微球(GO-HGM),经热还原得到具有导电能力的还原氧化石墨烯(RGO)包覆空心玻璃微球的功能化粉体(RGO-HGM),并将其应用到水性环氧富锌涂料中。用红外光谱仪(FT-IR)、拉曼光谱仪(Raman)、X射线光电子能谱仪(XPS)、扫描电镜(SEM)分析GO-HGM和RGO-HGM的结构和微观形貌,并通过电化学研究了涂层的防腐性能和防腐机理。结果表明:GO成功包覆到HGM表面上,且被热还原为RGO-HGM,并恢复一定的导电性。在含锌量50%的环氧富锌涂料中添加RGO-HGM,能有效提高活化锌含量,来提高环氧富锌涂层的阴极保护能力,且添加量为6%时,防腐效果最佳。To solve the dispersion problem of graphene in coating,graphene oxide-coated hollow glass microspheres(GO-HGM)were prepared using hollow glass microspheres(HGM)and graphene oxide(GO)as the raw materials.Then,through thermal reduction,functionalized powders(RGO-HGM)with electrical conductivity were obtained.The structure and microscopic morphology of GO-HGM and RGO-HGM were analyzed by FT-IR,Raman,XPS and SEM.The results showed that GO was successfully coated onto the surface of HGM and thermally reduced to RGO-HGM,restoring a certain level of conductivity.Adding RGO-HGM to epoxy zinc rich coatings with a zinc content of 50%could effectively increase the activated zinc content,thereby improving the cathodic protection ability of the epoxy zinc rich coating.The best anti-corrosion effect was achieved when the addition amount was 6%.
