Team of researchers from University of Illinois at Urbana-Champaign, Professors Scott White, Jeffrey S. Moore & Nancy Sottos and graduate students Brett Krull, Windy Santa Cruz & Ryan Gergely, have developed materials that not only heal, but regenerate. The new regenerating materials are capable to fill in large cracks and holes by regrowing materials. The team advanced their previous research on vascular materials and using specially formulated fibers that disintegrate, the researchers can create materials with networks of capillaries similar to biological circulatory systems. For regenerating materials, two adjoining, parallel capillaries are filled with regenerative chemicals that flow out as a result of damage. A gel is formed when the two liquids mix with each other, spreads and fills the gap created by the damage. Finally the gel hardens into a strong polymer and restores platic's mechanical strength. In addition to variety of commercial usage, these self-repair materials will find particular use for parts and products that are difficult to replace or repair, like in aerospace applications.
