DISPERSANT, PREPARATION METHOD THEREFOR, AND DISPERSION COMPOSITION OF CARBON-BASED MATERIALS, CONTAINING SAME

摘要

The present invention relates to a novel dispersing agent capable of uniformly dispersing a variety of carbon-based materials in different media including aqueous solvents and a preparation method thereof, and a carbon-based material-dispersed composition including the same. The dispersing agent is a mixture of a plurality of polyaromatic hydrocarbon oxides, and the mixture includes polyaromatic hydrocarbon oxide having a molecular weight of 300 to 1000 in an amount of 60% by weight or more.
