Method of coating a substrate with a graphene containing composition

摘要

A method of coating a substrate wherein a composition comprising graphene sheets and at least one polymer having a melting point or glass transition temperature of no greater than about 100° C. is applied to the substrate and the composition is cured at a temperature no greater than about 135° C. to form a coating.

主权项

1. A method of coating a substrate, comprising:
applying to the substrate a composition comprising graphene sheets, graphite, and a least one polymer having a melting point or glass transition temperature no higher than about 100° C., wherein the ratio by weight of graphite to graphene sheets is from about 50:50 to about 85:15; curing the composition at a temperature no greater than about 135° C. to form a coating; wherein the composition is applied to the substrate using one or more methods selected from the group consisting of: screen printing, gravure printing, offset printing, and flexographic printing; wherein the at least one polymer comprises an acid modified ethylene acrylate and/or an ethylene/methacrylic acid copolymer; and wherein the graphene sheets comprise atomic scale kinks.
