    摘要: A method for producing an EMI/RF absorbing material including dispersing metallic flakes in a resin. The method also includes providing a first coat of the resin containing dispersed metallic flake to form a first layer. The method further includes providing a second coat of the resin containing dispersed metallic flake to the first layer to form a second layer. At least one of the first or second layers has a substantially uniform distribution of metallic flake throughout a thickness of the first or second layers.
