<P>PROBLEM TO BE SOLVED: To provide membranes suitable as a separator which overcome one or more disadvantages of prior arts. <P>SOLUTION: A polymeric non-woven is treated with plasma, hereinafter shortened to plasma treatment, and a combination of at least two different adhesion promoters is subsequently used based on alkyltrialkoxysilanes wherein the alkyl group of one adhesion promoter comprises a substituent capable of reacting with a substituent of the alkyl group of the other adhesion promoter to form a covalent bond in the production of the ceramic coating, provide a coating which is notable for better adhesion compared with the prior art. Surprisingly, the ceramic coatings thus produced are not only very stable to the action of water, but are also pinhole free and resistant to abrasion. <P>COPYRIGHT: (C)2008,JPO&INPIT |
