Abstract
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.
Claims24
A method for de-bonding objects contained in an article at an interface between the objects, wherein the objects are joined at the interface through an intermediate layer, comprising:
- providing the article comprising the objects bonded at the interface through the intermediate layer, wherein the intermediate layer comprises an adhesive layer formed by curing a curable adhesive composition by application of a first x-ray source having a first x-ray energy, wherein the curable adhesive composition comprises one or more curable monomers and one or more energy modulation agents, whereby the one or more energy modulation agents convert the first x-ray energy into an initiation energy which initiates polymerization of the one or more monomers and thus cause curing of the curable adhesive composition;
- applying to the article a second x-ray energy from a second x-ray source, wherein the second x-ray energy is different from the first x-ray energy, and wherein the second x-ray energy is converted by the one or more energy modulation agents into an energy that is sufficient to cause destruction of bonds within the intermediate layer;
- and
- separating the objects from one another.
A method for preparing an article by bonding objects at an interface between the objects, wherein the objects are joined at the interface through an intermediate layer, comprising:
- providing an assembly of the objects having the intermediate layer at the interface thereof, wherein the intermediate layer comprises an adhesive layer comprising a curable adhesive composition, wherein the curable adhesive composition comprises one or more curable monomers and one or more energy modulation agents;
- applying a first x-ray source having a first x-ray energy, whereby the one or more energy modulation agents convert the first x-ray energy into an initiation energy which initiates polymerization of the one or more monomers and thus causes curing of the curable adhesive composition, thus bonding the objects together;
- wherein the one or more energy modulation agents contained in the intermediate layer of the bonded article can be used to separate the objects from one another by applying to the article a second x-ray energy from a second x-ray source, wherein the second x-ray energy is different from the first x-ray energy, and wherein the second x-ray energy is converted by the one or more energy modulation agents into an energy that is sufficient to cause destruction of bonds within the intermediate layer.
