摘要:
An article comprises a substrate and a functional polymeric phase change material bound to the substrate. In some aspects the functional polymeric phase change material is chemically bound to the substrate and can be accomplished by at least one of covalent bonding or electrovalent bonding. The functional polymeric phase change material can comprise a reactive function selected from the group consisting of an acid anhydride group, an alkenyl group, an alkynyl group, an alkyl group, an aldehyde group, an amide group, an amino group and their salts, a N-substituted amino group, an aziridine, an aryl group, a carbonyl group, a carboxy group and their salts, an epoxy group, an ester group, an ether group, a glycidyl group, a halo group, a hydride group, a hydroxy group, an isocyanate group, a thiol group, a disulfide group, a silyl or silane group, an urea group, and an urethane group, and wherein the substrate comprises at least one of cellulose, wool, fur, leather, polyester and nylon. Methods of producing the articles are also disclosed.
