    Electrochemical oxidation surface treatment of polyacrylonitrile-based carbon fibers (CFs) in 0.5M ammonium oxalate aqueous solution for 94s with the electric current density being 0.6mAcm−2 resulted in simultaneous improvements of interfacial bonding strength and tensile strength by ∼8.6% and ∼16.6%, respectively. The improvements were due to the following reasons: (1) besides creating active surface functional groups, the electrochemical oxidation treatment with
