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。

Abstract:To solve the dispersion problem of graphene in coating,raphene oxide-coated
g
hollow glass microspheres(GO-HGM)were prepared using hollow glass microspheres(HGM)
f
t
and graphene oxide(GO)as the raw materials. Then,hrough thermal reduction,unctionalized
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,estoring a certain level of conductivity. Adding RGO-HGM
r
to epoxy zinc rich coatings with a zinc content of 50% could effectively increase the activated
t
zinc content,hereby improving the cathodic protection ability of the epoxy zinc rich coating.
The best anti-corrosion effect was achieved when the addition amount was 6%.
