Moreover, the stiffness can be controlled
This amazing paper was created by scientists from two universities in Germany. In appearance, the paper sheet seems quite ordinary. But thanks to the nanotechnology applied in the production of this paper, under the influence of an electric current, it loses its rigidity and becomes completely soft. However, if the power is turned off, the stiffness of the sheet returns. When different voltage levels are applied, the stiffness of the paper also changes. Wood waste was used as raw material, from which cellulose nanoparticles are obtained.
The researchers plan to continue development, bringing the material to a level where the paper will be able to accumulate charge and release it when required. And this can find application in the manufacture of materials that can automatically “damp” shocks, for example, in a collision of cars, reports 3dnews.ru.
