  • Patent number: 10202484
    Abstract: A shape-memory self-healing polymeric network (SMSHP) is useful as a molded part, a coating, or as a matrix for a composite that can be repaired by heating to a controlled temperature. The SMSHP has thermally reversible repeating units where a thermally reversible adduct is situated between two common linking units formed during a polymerization process between thermally reversible monomers and cross-linking monomers. Optionally, other repeating units can be present from other monomers. Shape-memory results when the SMSHP is warmed to a temperature in excess of its glass transition temperature and self-healing then proceeds when a higher temperature is achieved where thermally reversible adducts dissociates to complementary groups that subsequently reform the adduct without distortion of the memorized shape. The thermally reversible adducts can be Diels-Alder (DA) adducts in a polyurethane, poly urea, or amine epoxy SMSHP network.

It satisfies the wide application demands and especially ensures such polymer can be used for beverage bottle, food package films, shopping bags and other food package containers. In addition, the method of preparation in present invention is simple, low-cost, and the raw materials are easily obtainable at low price. It is suitable for volume production and has practical value and application potentials.

  • Publication number: 20150093807
    Abstract: The present disclosure relates to a method for controlling degradation of biodegradable polyester. To be specific, biodegradation caused by a depolymerase is suppressed by capping a carboxyl terminal in biodegradable polyhydroxyalkanoate (PHA) having the carboxyl group at one terminal or its copolymer, and, thus, it is possible to easily suppress or control degradation depending on a capping ratio of the carboxyl group.
