▎ 摘　　要

NOVELTY - Colloidal suspension comprises: carbon nanomaterial; and an amine-metal complex compound having a substituent including a hydrocarbon, where the carbon nanomaterial and the amine-metal complex compound have dispersibility through non-covalent interactions between molecules. USE - The suspension is useful in adhesives, wiring electrodes, flexible/stretchable electrodes, conductive fibers, lightweight conductive wires, polymer composites, and electrodes for energy storage devices. ADVANTAGE - The suspension: has excellent dispersibility and complexation; and ensures high density and uniformity of metal particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the colloidal suspension comprising preparing a blended solution by adding a carbon nanomaterial and a metal precursor to an amine-containing solution, and stirring the mixed solution to form an amine-metal complex compound, and mixing the amine-metal complex compound with the carbon nanomaterial to prepare colloidal suspension.
