Abstract
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.
Claims19
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.
