ABSTRACT:
A stream of gas is forced through the pores of an object and either the gas itself or a component thereof is electrically activated through partial brush discharge such that reaction products will modify the surface of the pore walls as the gas flows through. The method avoids vacuum deposition methods as well as wet-coating methods and is applicable for either hydrophobizing or hydrophilizing objects and for improving, for example, biochemical activities or compatability of the object with a liquid to be filtered later.
