Abstract

The invention provides a double-sided wearable friction nanogenerator and a preparation method thereof. The friction nanogenerator comprises a first high-molecular polymer film layer, a friction electrode layer and a second high-molecular polymer friction film layer which are sequentially distributed in a stacked manner; a human body is taken as a second electrode and connected with the ground; the two layers of friction films are formed by flexible high-molecular polymers; nanostructures are modified on the outer surfaces; the flexible high-molecular polymer film layers can be worn on the human body and rub against the skin of the human body; and the friction electrode layer is a voltage and current output electrode of the friction nanogenerator. The flexible materials of which the surfaces are modified with the concave-convex nanostructures are utilized as two high-molecular polymer film layers, so that the roughness and the contact area of the friction surface are improved and more inductive charges are generated. According to the friction nanogenerator provided by the invention, by unique double-sided friction layer and flexible materials, energy in different directions can be collected and output of higher energy is achieved.
