The group of Akira HARADA at Osaka University has developed a new coating material based on polyrotaxane gliding materials. After cutting and scratching, over 80 % is repaired within 10 minutes, and the recovered film is solvent-free. Surface scratches recover within 30 minutes to nearly 100%. Wide applications are foreseen, from car repair to hemostatic coating sheets.
