  • New recipe for self-healing plastic includes dash of food additive


    • Close

      U. of I. researchers have improved a self-healing process originally described in 2001. In the new repair process, solvent-filled microcapsules that are embedded in an epoxy matrix rupture when a crack forms. The new solvent is non-toxic and less expensive. Researchers: from left, Jeffrey Moore, a professor of chemistry; Nancy Sottos, a professor of materials science and engineering; Scott White, a professor of aerospace engineering; and graduate research assistants Mary Caruso and Benjamin Blaiszik.
