  • Self-healing protocurable elastomers for additive manufacturing
    Patent number: 11920044
    Abstract: A method of making an ink for use in additive manufacturing of a self-healing product includes providing a thiol material. The method further includes oxidizing the thiol material to form a thiol-disulfide oligomer. The method further includes applying an alkene material to the thiol-disulfide oligomer to allow a thiol-ene reaction and form a self-healing ink embedded with a disulfide bond.
    Type: Grant
    Filed: February 19, 2020
    Date of Patent: March 5, 2024
    Assignee: UNIVERSITY OF SOUTHERN CALIFORNIA
    Inventors: Qiming Wang, Kunhao Yu
