  • Reflective silvered polyimide films via in situ thermal reduction silver (I) complexes
    Patent number: 6019926
    Abstract: Self-metallizing, flexible polyimide films with highly reflective surfaces are prepared by an in situ self-metallization procedure involving thermally initiated reduction of polymer-soluble silver(I) complexes. Polyamic acid solutions are doped with silver(I) acetate and solubilizing agents. Thermally curing the silver(I)-doped resins leads to flexible, metallized films which have reflectivities as high as 100%, abrasion-resistant surfaces, thermal stability and, in some cases, electrical conductivity, rendering them useful for space applications.

  • Low profile tactile switch
    Patent number: 5828016
    Abstract: A low profile tactile switch including a conductive member having a dome profile and lead means, a conductive contact member having a contact and lead means and an insulating member arranged between the conductive member and the contact member but allowing contact between the members upon actuation of the dome profile, wherein the switch may be mass produced from rolls of flat material.

  • Reflective self-metallizing polyimide films
    Patent number: 5677418
    Abstract: A silver organic complex, such as silver acetate, is solubilized in a polyamic acid resin or soluble polyimide solution using a suitable solvent such as hexafluoroacetyl acetone. The mixture is stable and can be applied to both flat and contoured surfaces. Application can be performed by casting, dip-coating, spraying, or other suitable techniques. In addition, the mixture can be cast or extruded as a polyimide film which is not applied to an underlying substrate. Upon curing, a flexible silver coated polyimide film is produced.
