Gas permeability of a high-density isotropic graphite block was reduced by coating the carbonization of aromatic polyimide by using a solution of polyamic acid. Imidization at 400ยฐC in nitrogen atmosphere after the solvent was vaporized out was essential for good adhesion with graphite substrate. By
