The invention provides a carbon material dispersant, a preparation method and application thereof. The carbon material dispersant comprises a linear block copolymer (PDMAEMA-b-PMA), a linear conductive polymer (PDMAEMA-b-PMA-b-PTh) ) and clathrate silsesquioxane OASQ star conducting polymers [OASQ‑(PDMA‑b‑PMA) 7 ‑PTh], the PDMAEMA‑b‑PMA, PDMAEMA‑b‑PMA‑b‑PTh and OASQ‑ The mass ratio of (PDMA-b-PMA) 7 -PTh is (1-50):(1-50):(40-80). The present invention improves the macromolecules of the carbon material dispersant in solution through the flexible poly-N,N-dimethylaminoethyl methacrylate segment in PDMAEMA-b-PMA and PDMAEMA-b-PMA-b-PTh stability, while utilizing the polythiophene conjugated segments in PDMAEMA‑b‑PMA‑b‑PTh to form a π‑π stacking effect with carbon materials, and utilizing OASQ‑(PDMA‑b‑PMA) 7 ‑PTh to tightly bond with carbon materials The materials stick together so that the carbon material is stably dispersed in the solution. |
