article description
Deposition/detachment of inorganic pigments (BiVO) by chemical bath deposition method (CBD) and polymer latex particles by impinging jet method on low temperature plasma treated polyethylene (PE), polypropylene (PP), polycarbonate (PC) and polystyrene (PS) were investigated. Bismuth vanadate (BiVO) coatings on the commercial polymer substrates were prepared by the thermal treatment of aqueous solutions containing a bismuth (III) ethylenediaminetetra-acetate chelate and vanadium (V) species. Ability to study and quantify deposition/detachment processes is of a high scientific and industrial importance. In this paper the (so called "impinging jet") apparatus for study of adsorption of spherical colloidal particles on different types of surfaces under controlled hydrodynamic conditions is described. In this comunication a chemical bath deposition method and impinging jet method as a two novel advanced techniques are discussed.
