Disclosed is a method for preparing self-dispersing nano carbon black based on a thiol-ene click reaction. A sol-gel technique is used to graft a coupling agent containing a carbon-carbon double bond onto the surface of the carbon black, and a functional molecular chain is grafted onto the surface of the carbon black by a thiol-ene click reaction with a mercapto compound. The self-dispersing nano carbon black is obtained after centrifugation, washing and drying. The method is simple and easy to operate, has a high grafting rate, and can prepare self-dispersing nano carbon black adaptable to different systems by selecting mercapto compounds with different functional groups.
A self-dispersing nano carbon black prepared by a thiol-ene click reaction, wherein the self-dispersing nano carbon black is obtained by first oxidatively modifying carbon black using a liquid phase oxidant to obtain oxidized carbon black, then reacting with a coupling agent to add a carbon-carbon double bond onto the surface of the oxidized carbon black, and finally grafting a functional molecular chain onto the surface of the carbon black by reacting with a mercapto compound through the thiol-ene click reaction.
