Abstract
The present invention encompasses materials and methods for catalyzing the cross-linking and curing of siloxane polymers. In particular, the present disclosure provides materials, methods, and conditions for vapor phase catalysis for curing organosiloxane polymers and resins, including resin linear organosiloxane block copolymers, as well as the incorporation of those methods into processes for making light emitting devices, including light emitting diodes.
Claims21
A method comprising:
- contacting a solid viscoelastic material with a first catalyst in a vapor phase, the solid viscoelastic material comprising an uncured polymer;
- and
- curing the uncured polymer after the solid viscoelastic material is contacted with the first catalyst in a vapor phase to provide a cured polymer.
The method according to claim 21, wherein:
- the solid viscoelastic material further comprises a second catalyst, and
- the second catalyst is inhibited by the particles.
A method comprising:
- providing a film comprising an uncured polymer and a particle of material, wherein the film is in a solid viscoelastic form;
- contacting the film with a catalyst in a vapor phase such that the catalyst infuses into the film to provide a treated film;
- and
- curing the uncured polymer after said contacting the film to provide a cured polymer.
