On demand radiation induced constructive and deconstructive chemical reactions
A method is provided for decomposition of a polymeric article, wherein the polymeric article contains a polymer and one or more energy modulation agents, by applying an applied energy to the polymeric article, wherein the one or more energy modulation agents convert the applied energy into an emitted energy sufficient to cause bond destruction within the polymer.
1. A method for depolymerization of a polymeric article, wherein the polymeric article comprises a polymer and one or more energy modulation agents, comprising:
applying an applied energy to the polymeric article, wherein the one or more energy modulation agents convert the applied energy into an emitted energy sufficient to cause depolymerization of the polymer, wherein the applied energy is x-rays, gamma rays, or electron beam and the emitted energy is UV.
2. The method of claim 1 , wherein the polymeric article is a rubber article.
3. The method of claim 2 , wherein the rubber article is a tire.
4. The method of claim 3 , wherein the tire has previously undergone vulcanization.
5. The method of claim 2 , wherein the rubber article has previously undergone vulcanization.
6. The method of claim 1 , wherein the polymeric article is in the form of a layer or film on a substrate, wherein the decomposition of the layer or film creates a pressure sensitive adhesive layer on the substrate.
7. The method of claim 1 , wherein the applied energy is x-rays.
8. The method of claim 7 , wherein the x-rays have an energy of 1 MV or higher.
