Underlying
Technology

  • Biomimicry: Self-healing bio-based materials are inspired by biological systems, such as the healing process of skin or the self-repairing capabilities of certain plants. Researchers are studying these natural mechanisms to develop similar functionalities in bio-based materials.
  • Microencapsulation: One common approach involves embedding microcapsules containing healing agents, such as monomers, catalysts, or bio-based resins, within the bio-based material matrix. When damage occurs, the microcapsules rupture, releasing the healing agents, which then react to repair the damage.
  • Vascular Networks: Inspired by the vascular systems found in living organisms, researchers are developing bio-based materials with embedded vascular networks that can transport healing agents to the site of damage.
  • Shape Memory Polymers: These bio-based polymers can be programmed to return to their original shape after deformation, offering a form of self-healing for shape recovery.
  • Bio-Inspired Self-Assembly: Leveraging the self-assembling properties of certain biomolecules, researchers are developing materials that can spontaneously reassemble and repair damage.
