Embodiment Construction

[0027] Embodiments of the present application will be described in detail below in conjunction with examples, but those skilled in the art will understand that the following examples are only used to illustrate the present application, and should not be considered as limiting the scope of the present application. Those who do not indicate the specific conditions in the examples are carried out according to the conventional conditions or the conditions suggested by the manufacturer. The reagents or instruments used were not indicated by the manufacturer, and they were all conventional products that could be purchased from the market.

[0028] In practice, the cracking temperature of acetylene is basically above 1400°C. Acetylene carbon black is obtained by subjecting acetylene to anaerobic cracking at the aforementioned cracking temperature. This reaction temperature (cracking temperature) determines that acetylene carbon black is a material that is more likely to stick togeth...

Abstract

The invention provides a method for modifying acetylene black, and belongs to the field of carbon materials. The method for modifying the acetylene black comprises the steps that the acetylene black is hybridized to add hydrophilic groups on the surface of the acetylene black, so that the acetylene black forms an amphipathic material. The intrinsic properties of the acetylene black prepared by themethod comprise improved dispersibility, thereby reducing the occurrence of agglomeration.

Description

technical field [0001] The present application relates to the field of conductive materials, in particular to a method for modifying and modifying acetylene carbon black. Background technique [0002] Acetylene black is an amorphous carbon. It is lightweight, has a large surface area, and has promising applications because of its conductive properties. However, the agglomeration property of acetylene black limits its application. Contents of the invention [0003] Based on the above deficiencies, the present application provides a method for modifying and modifying acetylene carbon black to partially or completely improve or even solve the problem of agglomeration of acetylene carbon black. [0004] This application is implemented like this: [0005] Modification methods of acetylene carbon black include: [0006] The acetylene carbon black is hybridized to increase hydrophilic groups on the surface of the acetylene carbon black so that the acetylene carbon black const...
