Germany's leibniz institute of polymer research team developed a special kind of graphene coating, the graphene coating can change color when it deformation or fracture, the papers published in "Material Horizons".
The team in the thesis describes the preparation of graphene coating method, and expounds their potential commercial value: used for artificial fault detection equipment and facilities.
Equipment, including aircraft and Bridges may suddenly fault occurs in the case of without warning. Before the fault, is proving to those relating to the personal safety facilities of exception is hard to be noticed.
Airplane wings and other parts, for example, in response to a certain suddenly applied stress produces micro cracks, the crack ?
