  • Bidirectional shape-memory polymer, method of its production and its use
    Patent number: 10040880
    Abstract: The present invention relates to an article consisting of or comprising a bidirectional shape-memory polymer (bSMP), the bSMP comprising: first phase-segregated domains (AD) having a first transition temperature (Tt,AD) corresponding to a crystallization transition or glass transition of the first domains (AD), second phase-segregated domains (SD) having a second transition temperature (Tt,AD) corresponding to a crystallization transition or glass transition of the second domains (SD), the second transition temperature (Tt,SD) being higher than the first transition temperature (Tt,AD), and covalent or physical bonds cross-linking the polymer chains of the bSMP, and in this way interconnecting the first and second domains (AD, SD), wherein the second phase-separated domains (SD) form a skeleton which is at least partially embedded in the first phase-segregated domains (AD), and wherein polymer chain segments of the bSMP forming the first domains (AD) are substantially orientated in a common direction, such tha

    Date of Patent: August 7, 2018
    Assignee: Helmholtz-Zentrum Geesthacht Zentrum fuer Material -und Kuestenforschung GmbH
    Inventors: Marc Behl, Karl Kratz, Ulrich Noechel, Tilman Sauter, Joerg Zotzmann, Srinivasa Reddy Chaganti, Andreas Lendlein
  • Method of preparing a bidirectional shape-memory actuator and method of its use
    Patent number: 9919470
    Abstract: The present invention is directed to a method of preparing an actuator capable of being repeatedly and reversibly shifted between two freestanding shapes (A, B) under stress-free conditions upon varying a temperature between a temperature Tlow and a temperature Tsep.
