Large, self‐supporting graphite films (e.g., see Figure) have been prepared using phosphate‐treated montmorillonite, a clay, as a template. The preparation—intercalation of the montmorillonite with a copolymer from an aqueous dispersion, conversion of the copolymer component to amorphous carbon, heat treatment to give a highly oriented graphite film—and characterization of the films are described.
