Abstract

The present disclosure generally describes techniques suitable for use in the construction or recycling of composite materials. An article may comprise a thermoplastic coupled to a bonding interface layer, with a coating layer applied to the surface of the bonding interface layer. A bonding interface layer may comprise catalytic nanoparticles embedded within and/or encapsulated by one or more radiatively unstable polymers. Application of ionizing radiation to the article may release a catalyst at the bonding interface. Application of heat and/or stress to the article may enhance catalytic degradation of the remaining bonding interface and uncoupling of the thermoplastic from the coating layer. Embodiments of methods, compositions, articles and/or systems may be disclosed and claimed.
