The invention relates to a polymer hyperdispersant and a preparation method and application thereof, perylene-3, 4, 9, 10-tetracarboxylic dianhydride and polyether amine are used as reaction raw materials to react under an alkaline substance condition to form a carboxylate-containing perylene amide acidified polyether dispersant, the structural formula of the carboxylate-containing perylene amide acidified polyether dispersant is # imgabs 0 # imgabs 1 #, and n is an integer of 20-50. The perylene amide acidified polyether dispersant is creatively prepared on the basis of conventional raw materials perylene-3, 4, 9, 10-tetracarboxylic dianhydride and polyether amine, perylene functional groups in the dispersant are connected with polyether through amido bonds, carboxylate is formed at the same time, and the perylene amide acidified polyether dispersant has the advantages that the raw materials are easy to obtain, synthesis is simple, and large-scale production is easy; perylene, a carbon nanomaterial and a con
