Advanced polymer coatings for busbar applications

Abstract

A multilayer Busbar coating system, in which individual layers are tailored to address functional requirements of electrical insulation, thermal conductivity, EMI shielding and corrosion resistance. A conductive metal core, including any of a Copper or Aluminum, is provided, over which is applied at least one polymer based layer incorporating a Graphene, functionalized Graphene, carbon nanotube, nano-material, MXene material or electrically conductive filler. In a preferred embodiment, a first thermally conducting polymer insulation layer coating is applied over the conductive metal core, with a second EMI resistant layer applied over the first insulation layer. At least one of the polymer layers further includes any of a flame retardant or intumescent coating.
