Title:

DISPERSANT FOR NANOCARBON, AND NANOCARBON DISPERSED MATERIAL

Document Type and Number:

Japanese Patent JP2018001100

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a dispersant for nanocarbon capable of obtaining nanocarbon dispersed material in which the nanocarbon is minutely dispersed.SOLUTION: A dispersant for nanocarbon comprises following component (A) and component (B). In the dispersant, a content of the component (B) is 100 to 40 mol% with respect to carboxyl group of the component (A). Component (A) is a copolymer which contains a unit (a) derived from maleic acids and a unit (b) derived from a polyoxyalkylene compound represented by a formula (I): RO(AO)R[in the formula, Ris an alkenyl group having carbon number of 2 to 8, Ris hydrogen atom or a saturated hydrocarbon group having carbon number of 1 to 18, AO represents an oxyalkylene group having carbon number of 2 to 4, and n denotes average addition mol number of oxyalkylene group per one molecule and is 1 to 100], or contains a unit (c) derived from styrenes in accompany with such two units, composition ratio of them being (a) 85 to 45 mol%, (b) 50 to 15 mol%, and (c) 5 to 0 mol%, and weight average molecular weight being 1,000 to 100,000. Component (B) is at least one kind selected from alkali metal and ammonia.SELECTED DRAWING: None
