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.
