Abstract

1399213 Carbon-containing membranes; laminates H D WRIGHT 1 June 1972 [2 June 1971] 25725/72 Headings B5B and B5N [Also in Divisions C3 C1 and C7] A gas permeable but liquid impermeable membrane is produced by mixing together finely-divided carbon and particles of a fluorocarbon polymer and sintering the mass. Preferably the fluorocarbon is polytetrafluoroethylene, and the carbon acetylene black or activated charcoal. In a preferrd process, the carbon is mixed with an aqueous dispersion of the fluorocarbon to form a homogenoeus slurry which is then formed into a sheet which is heated to remove water and then sintered. The drying step may be assisted by rolling. The membrane may be laminated to a gauze of nickel and stainless steel, or to another membrane, this one containing graphite and polytetrafluoroethylene. This gives an electrical contact and allows the membrane to be used as a cathode in electrolysis.
