Abstract
A method for coloring a carbon nanotube (CNT) product is provided, including placing a CNT product in an electric circuit to ground the product, charging a plurality of pigment molecules with an opposite charge from the CNT product, applying a coating of the charged pigment molecules to a surface of the CNT product, and exposing the coating to a temperature sufficient to cure the coating, while allowing the coating to form a substantially conformal film on the surface of the CNT product.
