Method for modifying composite surface of carbon fiber

The invention discloses a method for modifying the composite surface of a carbon fiber (CF), which relates to a double-surface processing method of the CF. The method comprises the following two steps: (1) carrying out nitric acid liquid-phase oxidization on the CF to improve the surface biocompatibility of the CF; and (2) immersing the oxidized CF in an iron chloride or calcium chloride solution to adsorb metal cations so as to improve the adhesion strength of microorganisms on the surface of the CF. The invention can effectively increase the adhesion quantity and the adhesion strength of microorganisms on the surface of the CF, thereby being beneficial to the CF as the biological film carrier used for sewage treatment based on a biological film method and other relevant fields.
