▎ 摘  要

NOVELTY - Increasing electrical and thermal conductivity of a textile article involves applying a composition comprising (a) 10-40 wt.% polymeric binder, (b) 1-10 wt.% compatibilizing solvent for the polymeric binder, (c) 0.1-2 wt.% thickener, (d) 1-20 wt.% graphene containing at least 90% graphene nanoplatelets having lateral dimension (x,y) of 50-50000 nm, thickness (z) of 0.34-50 nm and containing carbon/oxygen ratio of more than 100:1, (e) 40-80 wt.% water, and (f) 1-40 wt.% inorganic pigment on the textile article. USE - Increasing electrical and thermal conductivity of textile article (claimed) e.g. seats and sofas. ADVANTAGE - The effective, simple and economical method maintains thermal conductivity, reduces surface resistivity, and increases electrical conductivity, of over one order of magnitude. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composition. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the textile article.
