Researchers in Hyderabad, India, have discovered that sheets of graphene have unexpected "self-healing' properties. After first subjecting sheets containing various defects to tensile stresses, they found that the broken graphene bonds in the defective areas began to rebuild themselves once the stresses were relaxed. “We were able to document the self-healing of cracks in graphene without the presence of any external stimulus and at room temperature,” said Dr. Swati Ghosh Acharyya, the main author of the article, which was published in Open Physics. Graphene is a two-dimensional material consisting of carbon atoms arranged into hexagonal sheets.

The property could lead to artificial, self-healing skin for robots being developed.
