Gel that Will Heal Skin Completely in 24 Hours
The secret of the material lies not only in the organized arrangement of the nanosheets, but also in the polymers that are entangled between them. Postdoctoral researcher Chen Liang mixed a powder of monomers with water that contains nanosheets. The mixture was then placed under a UV lamp.
‘Entanglement means that the thin polymer layers start to twist around each other like tiny wool yarns, but in a random order,’ adds Hang Zhang, from Aalto University.
Four hours after cutting it with a knife, the material is already 80 or 90 percent self-healed. After 24 hours, it is typically completely repaired. Furthermore, a one-millimetre-thick hydrogel contains 10,000 layers of nanosheets, which makes the material as stiff as human skin, and gives it a comparable degree of stretch and flexibility.
