Abstract

The invention provides a friction nano generator and a preparation method thereof, and a wearable device. The preparation method comprises the following steps of: preparing a polymer fiber reticular membrane serving as an electronegative friction layer by using an electrostatic spinning method; preparing a reduced graphene oxide solution, or a reduced graphene oxide hybrid solution in which metalnanoparticles or semiconductor nanoparticles are loaded on reduced graphene oxide; loading the reduced graphene oxide solution or the reduced graphene oxide hybrid solution on the polymer fiber reticular membrane in a suction filtration mode to form a reduced graphene oxide membrane or a reduced graphene oxide hybrid membrane on the polymer fiber reticular membrane, and taking the reduced grapheneoxide membrane or the reduced graphene oxide hybrid membrane as a charge enhancement output layer; preparing a second electrode layer as an electropositive friction layer; and taking the charge enhancement output layer and the electronegative friction layer as one body to be electrically connected with the second electrode layer to form a preset distance so as to obtain a friction nano generator.Therefore, the electrical output of the friction nanometer generator is greatly improved.

Description

technical field [0001] The invention relates to the field of nano energy technology, in particular to a friction nano generator, a preparation method thereof, and a wearable device. Background technique [0002] Triboelectric nanogenerators based on the principles of triboelectricity and electrostatic induction are developing very rapidly. Due to their simple manufacturing process, cheap and easy-to-obtain materials, light devices and high conversion efficiency, they will become a choice for future mechanical power generation. However, before nanogenerators can be used as practical green power sources for large-scale applications, their performance, including output performance and durability, must be significantly improved through rational design. Continuously seeking ways to improve the output performance of triboelectric nanogenerators has always been the goal of researchers trying to effectively harvest mechanical energy. One way to achieve this goal is to optimize mater...
