Method of forming a thin unbacked metal foil
Patent
·
OSTI ID:5827019
In a method of forming a thin (<2..mu..m) unbacked metal foil having a desired curviplanar shape, a soluble polymeric film, preferably comprising polyvinyl alcohol, is formed on a supporting structure having a shape that defines the desired shape of the foil product. A layer of metal foil is deposited onto one side of the soluble film, preferably by vacuum vapor deposition. The metallized film is then immersed in a suitable solvent to dissolve the film and thereby leave the metal foil as an unbacked metal foil element mounted on the supporting structure. Aluminum foils less than 0.2 ..mu..m (2,000 A) thick and having an areal density of less than 54 ..mu..g/cm/sup 2/ have been obtained.
