摘      要：This work was dedicated to performing surface oxidation and coating treatments on carbon fibers （CF） and investigating the changes of fiber surface properties after these treatments, including surface composition, relative volume of functional groups, and surface topography with X-ray photoelectron spectroscopy （XPS） and atom force microscopy （AFM） technology. The results show that, after oxidation treatments, interfacial properties between CF and non-polar polyarylacetylene （PAA） resin are remarkably modified by removing weak surface layers and increasing fiber surface roughness. Coating treatment by high char phenolic resin solution after oxidation makes interface of CF/PAA composites to be upgraded and the interfacial properties further bettered.
