LIQUID PRESSURE IMPERMEABLE CATION EXCHANGE MEMBRANES AND ITS MANUFACTURE |
摘要 |
<p>Disclosed is an improved hydraulically impermeable cation exchange membrane for an electrolytic cell and a method for the preparation of such a membrane using a copolymeric substrate and applying to the surface thereof by means of plasma polymerization, a very thin top coating of a second polymeric material to drastically reduce the permeability of the substrate material with a minimal effect upon the bulk properties of the resultant membrane. Such top coatings may be applied over the basic substrate or over surface treated substrates to enhance the chemical resistivity of the membrane to chemical breakdown occasioned by the electrolyte within the electrolytic cell.</p> |
