Investigation on the recovery performance of olefin block copolymer/hexadecane form stable phase change materials with shape memory properties

Recovery performance of a novel sort of FSPCMs with simultaneously shape memory properties, which comprise hexadecane and OBC, was investigated systematically. The in situ WAXS and SAXS characterization of structural change during deformation shows the recovery performances are closely correlated to OBC crystalline morphologies, and the irreversible deformation of the difunctional materials might originate from lamellar fragmentation of OBC.393
