Human skin has an amazing capacity to heal itself from scratches and cuts, so it’s not surprising that scientists are looking at transferring the self-healing properties of skin to industrial materials. Efforts to embed tiny liquid-filled capsules that rupture when a scratch occurs to spill healing agents into the damaged area of electroplated coatings have previously been hampered by the size of these capsules. But now researchers have developed a process for producing electroplated layers with nano-capsules that measure only a few hundred nanometers in diameter that could solve the problem.
I can imagine how a lobster might scratch a car, but who would ever have thought of using one to repair a scratch in your paint? Scientists have recently developed a polyurethane coating that heals its own scratches when exposed to sunlight.
