Fabrication of sub micrometric sieves consists of holography, photogravure based on photo resins and metal based electroforming, for filtration

NOVELTY – The fabrication of sub-micrometric sieves comprises holographic exposure for photogravure of a high-performance mask of photo-resins and electroforming using metal. Also claimed is the product of the process. CLAIMED PRODUCT – The product has a transparent substrate coated with conducting material, which is removed prior to use in micro-filtration and e.g. emulsions production. USE – In Chemical engineering.

Main Application Field

J01 (Separation – including evaporation, crystallisation, solvent extraction, chromatography, dialysis, osmosis including drying gases and/or vapours, and separation of solids from gases, liquids and other solids. Isotope separation, filter materials (including molecular sieves for separation), and centrifuges (except where used for analysis) (B01D, B03, B04, B07B).)
