Abstract
Disclosed herein is a conductive coating composition that includes a functionalized carbon nanomaterial and/or boron nanomaterial and a fluid component. The nanomaterial and fluid component forms hydrogen bond network in the disclosed composition. Because of the formed hydrogen bonds, the disclosed coating exhibits enhanced thermal or electrical conductivity. Also disclosed is a method to improve thermal or electrical conductivity of an existing coating composition.
Claims20
A conductive coating composition comprising:
- from about 25 wt-% to about 99 wt-% of a fluid component comprising a polyacrylic acid, polyol, polyurethane, water-based epoxy, water, or a mixture thereof;
- wherein the fluid component comprises a polymer and wherein the fluid component comprises one or more of a second functional group capable of forming a hydrogen bond;
- and
- from about 0.5 wt-% to about 20 wt-% a nanomaterial;
- wherein the nanomaterial is a carbon nanomaterial having one or more of a first functional group capable of forming a hydrogen bond or a boron nanomaterial.
A method of enhancing thermal or electric conductivity of a coating composition comprising:
- adding into a coating composition a nanomaterial to form an improved coating composition, wherein the nanomaterial is a carbon nanomaterial having one or more of a first functional group or a boron nanomaterial capable of forming a hydrogen bond with a second functional group in the coating composition;
- passing the improved coating composition through a roller mill, an extruder, a manual stirrer, and/or a mechanical stirrer to form the conductive coating composition.
