Abstract
Corrosion resistant metallized films and methods of making the same are disclosed.
Claims37
A corrosion-resistant metallized film comprising:
- a polymeric primer layer having a first surface;
- a metal layer adjacent the first surface of the polymeric primer layer;
- and
- a polymeric protective layer adjacent the metal layer, said protective layer having a second surface in contact with the metal layer;
- wherein the first and second surfaces (i) have a similar surface charge, and (ii) jointly provide corrosion resistance to the metal layer.
2 more elements
A method of forming a corrosion-resistant metallized film, said method comprising the steps of:
- providing a polymeric protective layer having a first surface with an overall positive or negative surface charge;
- depositing a metal layer on the first surface, said depositing step being terminated prior to or shortly after an onset of conductance within the metal layer;
- and
- applying a polymeric primer layer over the metal layer, said polymeric primer layer comprising a second surface in contact with the metal layer, wherein the second surface has an overall surface charge similar to the first surface.
