摘      要：An organic/inorganic hybrid coating with self-healable hydrophobicity is prepared as triboelectrical layer by micro-arc oxidation(MAO)and fluorinated sol-gel(FSG)*** MAO/FSG hybrid coating-based TENG(MF-TENG)has a current output of31μA and voltage output of 870 V,which is eight times that of the MAO based *** with organic coating,the organic/inorganic hybrid coating has good wear *** the fluorine composition on the surface of the coating is damaged,the self-healing hydrophobicity and electrical output are achieved by transferring loaded perfluorosilane to the damaged *** fluorinated sol-gel coating is hydrophobic,which ensures that the coating has good corrosion ***,the electricity generated in triboelectrification could improve the anti-corrosion performance by cathodic *** on the anti-corrosion,anti-wear and self-healing properties,the MF-TENG has potential applicability in the field of energy collection,energy supply,and corrosion protection.
