▎ 摘  要

NOVELTY - Composition comprises 35-85 wt.% first dispersion, and 15-65 wt.% second dispersion. The first dispersion comprises 30-90 wt.% graphene powder, 1-35 wt.% first binder and 1-35 wt.% additives. The second dispersion comprises 25-75 wt.% metal nanowires and 25-75 wt.% second binder. The first binder and the second binder include emulsion or dispersion containing acrylic copolymer, acrylic urethane or polyurethane. The additive is polymer having positive charge. USE - The composition is useful for coating transparent conductive film (claimed). ADVANTAGE - The composition provides transparent conductive film having high dispersibility, high conductivity, and excellent optical and electrical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composition, comprising (a) mixing graphene powder, first binder and additives to obtain first dispersion, (b) mixing metal nanowires and second binder to obtain second dispersion, and (c) mixing the first dispersion and the second dispersion.
