Low-density polyethylene films strained up to 35% exhibit an initial increase of diffusivity and permeability which soon reach a maximum and subsequently drop to steadily decreasing values below those of the unstrained starting material. The sorption steadily increases and seems to approach a platea
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 400Β°C in nitrogen atmosphere after the solvent was vaporized out was essential for good adhesion with graphite substrate. By
