NOVELTY - Coating a substrate involves adding a nanocarbon material to an electrophoretic solution in an electrophoretic deposition apparatus including the substrate and an electrode spaced from the substrate. A current is applied to the substrate and the electrode to deposit the nanocarbon material onto the substrate. USE - Method for coating a substrate by nanocarbons with a variety of geometries as functional coatings for stray and reflected light suppression. The Low-reflectivity coating can be used in fields of aerospace, energy, military, defense, and daily life, such as baffles for minimizing stray light to improve the resolution of a space telescope and the sensitivity of exo-atmospheric optical sensors for missile defense and satellite-based surveillance systems, and solar absorbers for solar thermal power generation. ADVANTAGE - A low-cost and scalable nanocarbon coating method is provided, for uniformly applying nanocarbon coatings to planar and irregularly shaped surfaces. The nanocarbon coating to a plasma treatment to enhance the nanocarbon coating properties. An electrophoretic deposition (EPD) process, based on the use of pulsed electric fields, provides for controlled, reproducible, scalable, uniform deposition nanocarbon coatings comprising CNTs, graphene, and mixtures. The nanocarbon coatings can enhance the low-reflectivity properties of planar and non-planar substrates.
