▎ 摘　　要

NOVELTY - Dispersion of particles comprises a particles, a polydopamine, and a water-soluble polymer containing an amino groups, where the dispersion is alkaline. USE - The dispersion of particles is used for controlling surface potential of particles in an aqueous solution. ADVANTAGE - The dispersion of particles does not use fluorine-based surfactant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for dispersing particles in an aqueous solution, involving dispersing particles in an alkaline aqueous solution containing polydopamine and a water-soluble polymer containing an amino group.
