Self-healing graphene could make robots that fix themselves with water

Adding graphene to a gel makes a 3D-printable substance that dries to be strong and conductive and heals when wet

Home News Physics Technology Daily news 26 July 2018 Self-healing graphene could make robots that fix themselves with water Graphene has a number of useful propertiesShuyuan Lin, Yujia Zhong et al.By Leah CraneGraphene, an atom-thick layer of carbon, has been called a miracle solution for better batteries, stronger armour, flexible electronics, and more. Now a self-healing version could do even more. Hongwei Zhu at Tsinghua University in China and his colleagues have made a graphene gel that is tough and rigid when dry, but squidgy, stretchy and self-healing when wet. They mixed graphene sheets, just a nanometre thick, with water, then added polyacrylic acid, which has good water-absorbing properties. This created an interconnected network of graphene … Popular Robots and AI will actually create more jobs than they take Warming Arctic could be behind heatwave sweeping northern hemisphere No, mobile phones still won’t give you brain cancer Advertisement googletag.cmd.push(function () { googletag.display('mpu-sidebar'); });
