  • Self-healing polymeric material synthesized by guiding magnetic microcapsules
    Patent number: 10179846
    Abstract: A process of making magnetic microcapsules and a process of making polymeric material having self-healing properties. The process of making polymeric material having self-healing properties includes the steps of mixing microcapsules containing magnetic nanoparticles in a liquid polymer before curing, and guiding the microcapsules in the liquid polymer before curing by magnetic forces to a desired location or locations. Finally, the liquid polymer with the microcapsules is cured to a solid polymeric material.
