in a catalytic coating experiment, steel fibers (stainless steel) will be coated with catalytic active CuO either through
a) Sol gel methode or
b) wet impregnation onto an intermediate coating
The exact surface condition of the steel fibers is unknown. In order to promote the adhesion of the sol/intermediate coating onto the surface of the steel fibers and to ensure the reproducubility of the tests, the steel fiber surface should be cleaned prior to coating.
If i wish to remove contaminants from the surface of the steel fibers surface without risking secondary contamination during the cleaning, which cleaning procedures are recommended?
Toulene can be used to clean.it evaporates easily and there will not be any traces of it.
You can use chemical method to clean steel fibers and more than chemical method or acid uses.
The kind of surface cleaning method to be employed would depend upon the nature of materials earlier deposited on the fiber surface and the degree of surface heterogeneity required for better adhesion of the catalyst. If the organic solvent like acetone, toluene cleaning doesn't work acid pickling may be tried.
