| titleOfInvention | Carbon material dispersant, method for producing the same, and stable aqueous dispersion of carbon material containing the dispersant |
| abstract | The present invention relates to a carbon material dispersant, a method for producing the same, and a stable aqueous dispersion of a carbon material containing the dispersant. In particular, the dispersant is suitable for dispersing carbon materials having a graphene structure, comprising an amphiphilic hyperbranched polymer having a backbone structure comprising amine groups and a monocyclic, polycyclic, fused or heterocyclic aryl group covalently bonded to the backbone structure that is non-covalently associated with the graphene structure. The carbon material dispersant is prepared by the following steps: i) reacting a polyglycidyl compound with a polyfunctional amine, thereby forming a hyperbranched polymer having a secondary amine group at a terminal, wherein the amino hydrogen of the polyfunctional amine is in molar excess relative to the glycidyl groups of the polyglycidyl compound; and ii) introducing a monocyclic, polycyclic, fused ring, or heterocyclic aromatic group non-covalently associated with the graphene structure into the hyperbranched polymer via reaction with a secondary amine group, thereby forming a dispersant comprising an amphiphilic hyperbranched polymer. |
