The present disclosure generally describes techniques suitable for use in the construction or recycling of composite materials, such as thermoplastics. A coated thermoplastic article may comprise a thermoplastic portion coupled to a supramolecular polymer interface layer, with a coating layer applied to a surface of the supramolecular polymer interface layer. Application of heat to the coated thermoplastic article may cause the supramolecular polymer interface layer to undergo a phase change, allowing the coating layer to be removed from the thermoplastic portion. Application of force to the coated thermoplastic article may enhance the removal of the coating layer. Embodiments of methods, compositions, articles and/or systems may be disclosed and claimed.
