摘要：
Super-hydrophobic polyhedral oligomeric silsesquioxane functionalized graphene oxide (GP) was synthesized by one-step condensation reaction. Addition of 0.5 wt% GP into epoxy matrix (0.5 wt% GP/EP) could enhance the impedance by 2 orders of magnitude after 150 days immersion compared with pure epoxy (EP) coating. Moreover, the 0.5 wt% GP/EP specimen displayed better lubrication properties than EP, 0.5 wt% GO/EP, and 1 wt% GP/EP composites. Such outstanding anti-corrosion and wear-resistant abilities were ascribed to the comprehensive action of repellent GP with excellent shielding effect, the self-lubrication of GP with well dispersibility and the great improvement of mechanical property.
