Abstract In this article, we demonstrate the fabrication of thin and macroporous carbon coatings that adhere to various metal substrates such as nickel- or aluminum-based foils meshes. The coating process is a combination emulsion-templating doctor-blade method, which allows prepare up 350 µm thick poly(dicyclopentadiene) membranes with polyHIPE (polymerized high internal phase emulsions) archi...
