Abstract

An article comprises a substrate, a first functional polymeric phase change material, and a plurality of containment structures that contain the first functional polymeric phase change material. The article may further comprise a second phase change material chemically bound to at least one of the plurality of containment structures or the substrate. In certain embodiments, the article further comprises a second phase change material and a binder that contains at least one of the first polymeric phase change material and the second phase change material. The containment structure may be a microcapsule or a particulate confinement material.
