The only application I am aware of is using tannins to promote self-cleaning (through layering formation) of different kind of surfaces.

Self-healing materials are highly engineered that mimic the functionalities of various natural materials found in the human body (e.g., the healing of skin and bones by the vascular system, Lotus plant leaves and water striders, snake skin ). The self-healing material used is encapsulation technologies to incorporate healing materials. The encapsulated healing materials (Micro or nano particles) are randomly distributed inside the matrix materials. Whenever any kind of damage happened on the surface of the self-healing materials due to mechanical, abrasive, chemical reaction, the encapsulated healing agents release that allow patching up the damage.

The technology has multiple applications in different fields

  • Construction materials – Self healing cement
  • Paints or coatings– Self healing paints, self-cleaning surface
  • New generation of self-repairing, tissue-adhesive and tough hydrogel, Self-healing photoreceptor
  • Superoleophobic surfaces that exhibit self-cleaning, antifouling, low-drag, and anti-smudge properties
  • Self-healing materials in health care- Biomedical application of self-healing gels
  • Bio-inspired Self-Healing Organic Materials - Bio-similar, Self Fixing Assembled Bone-Tendon
  • Automotive industry - Self-sealing vehicle tire and sealant composition
  • Garment industry - self repairing clothes, Self-cleaning cloths
  • Metallurgy
  • Communication


Some organizations working on the area

  • Ethicon Endo-Surgery, Llc
  • Angiotech Pharmaceuticals, Inc.
  • Searete Llc,
  • Broncus Technologies, Inc.
  • Academic institutes across the globe
