                      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)

                 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%.
