Zirconia(ZrO2) was uniformly doped in the carbon fiber (CNF) through the electrospinning method. In addition, the as-prepared zirconia doped carbon fiber (ZrO2-CNF) were modified with gamma-(2,3-epoxypropoxy)propytrimethoxysilane (KH560) in order to improve the dispersion in the epoxy resin, then the ZrO2-CNF/epoxy composite coatings were prepared. The morphology and structure of ZrO2-CNF composites fiber were characterized through SEM, EDS-Mapping, TEM, FT-IR and XPS. Besides, the mechanical properties of ZrO2-CNF/ epoxy composite coatings were tested by Tensile test, and the corrosion resistance properties of the composite coatings were characterized by means of electrochemical impedance spectroscopy (EIS) and polarization curves analysis. The results show that the ZrO2 could be doped on the CNF uniformly, and fiber with uniform size can be obtained. Then the corrosion resistance properties and mechanical properties of the ZrO2-CNF/epoxy composite coatings were enhanced effectively due to excellent hardness and corrosion resistance of ZrO2.
