Abstract

The invention discloses a surface processing method of a carbon fabric. The surface processing method comprises the steps of liquid phase oxidization processing of the carbon fabric, electro-deposition processing and laser photoetching. A mode of electro-deposition processing and laser photoetching is performed on the basis of liquid phase oxidization processing, laser photoetching is performed ona carbon fabric surface after electro-deposition processing by a laser photoetching machine, the purposes of improving surface activity, further expanding specific area of the carbon fabric and enriching a surface hole structure are achieved, so that the technical effect of improving the electrochemical performance of the carbon fabric is achieved, and the technical problem that the electrochemical performance of the carbon fabric is not improved a lot only by a liquid-phase oxidization method of the carbon fabric processing method in the prior art to cause that the demand of a supercapacitorelectrode cannot be satisfied is further solved.

Description

technical field [0001] This application relates to the field of communication, in particular, to a method for surface treatment of carbon cloth. Background technique [0002] Carbon Cloth, the abbreviation of carbon fiber cloth, is made of pre-oxidized polyacrylonitrile fiber fabric through carbonization or carbon fiber weaving, also known as carbon fiber cloth, carbon fiber fabric, carbon fiber tape, carbon fiber sheet (prepreg) Wait. At present, carbon cloth is mainly used in the fields of electrochemistry, microbial fuel cells, supercapacitors and lithium batteries. Among them, carbon cloth is often used as an electrode in a supercapacitor. [0003] Supercapacitor refers to a new type of energy storage device between traditional capacitors and rechargeable batteries. It not only has the characteristics of fast charging and discharging of capacitors, but also has the characteristics of energy storage of batteries. A new type of component for storing energy with an inter...
