Abstract
A material for energy management and peak energy reduction in a building structure, comprises an insulative base material, a first phase change material, and a functional polymeric phase change material that dynamically absorbs and releases heat to adjust heat transfer. The functional polymeric phase change material has at least one phase change temperature in the range between −10° C. and 100° C. and a phase change enthalpy of at least 5 Joules per gram, the functional polymeric phase change material including a plurality of polymer chains that include a backbone chain and a plurality of side chains, wherein a first portion of the plurality of polymer chains are crosslinked to each other, wherein a second portion of the plurality of polymer chains are crosslinked with the first phase change material and a third portion of the plurality of side chains are mechanically entangled with the inorganic insulative base material.
