  • Partially degradable fibers and microvascular materials formed from the fibers
    Patent number: 11155940
    Abstract: A partially degradable polymeric fiber includes a thermally degradable polymeric core and a coating surrounding at least a portion of the core. The thermally degradable polymeric core includes a polymeric matrix including a poly(hydroxy-alkanoate), and a metal selected from the group consisting of an alkali earth metal and a transition metal, in the core polymeric matrix. The concentration of the metal in the polymeric matrix is at least 0.1 wt %. The partially degradable polymeric fiber may be used to form a microvascular system containing one or more microfluidic channels.
    Type: Grant
    Filed: June 1, 2018
    Date of Patent: October 26, 2021
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Hefei Dong, Stephen J. Pety, Nancy R. Sottos, Jeffrey S. Moore, Scott R. White
