METHOD FOR PRODUCING PVD ANTI-BACTERIAL FILM ON PLASTIC

摘要

The invention provides a method for producing a PVD anti-bacterial film on plastic. By adoption of the technical scheme, film plating can be achieved on the premise of not damaging a plastic workpiece without heating during the whole process, and a titanium target and a silicon target are used for plating a base film; plastic mainly contains a large quantity of carbon atoms and silicon atoms and has good bonding force, so that the bonding force of the film and the workpiece can be increased by plating the base film through the titanium target and the silicon target; a silver target is added for sputtering after the base film is plated, so that silver with an anti-bacterial effect is evenly distributed in a titanium silicide film, and the anti-bacterial film with the anti-bacterial effect is formed.
