Document Type and Number:
Japanese Patent JP6512574
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous dispersion of a nanocarbon material where the nanocarbon material can be homogeneously dispersed into an aqueous solvent without impairing handling ability and the fault of the nanocarbon material after producing the dispersion can be reduced, a production method of the same and a dispersant used for the same.SOLUTION: A dispersant for an aqueous dispersion of a nanocarbon material is represented by formula (I) (where, Ris a 1-22C alkyl group; Ris a 1-22C alkylene group; Ris a 1-22C alkyl group; the carbon number of R-CH-CH-R- is selected to be 9-25 in Rand R; X and Y exhibit a sulfate ester, their salts or the like; and Z exhibit -O-C(=O)-, -C(=O)-O-, -NH-C(=O)- or -O-).
