Embodiment 1

[0082] Such as Figure 5 As shown, the nano friction generator of this embodiment is an opaque hollow ball, and the ball radius of the power generating ball is 2 cm. The triboelectric generator includes three layers, a first electrode layer 51, a high molecular polymer layer 52 disposed on the first electrode, and a second electrode layer 53 disposed on the high polymer layer. The preparation method is as follows:

[0083] (1) Preparation of the hollow sphere core: The hollow sphere core is prepared by the conventional template method. Specifically, the sacrificial silicon sphere is used as the template to copolymerize styrene and KH570 monomer through the dispersion polymerization method. The SiOH group is introduced into the surface of the PSt latex particles through chemical bonds, and then an ethanol solution of butyl silicate (TEOS) is added dropwise to cause the TEOS to undergo polycondensation reaction with the copolymer obtained in the previous step, thereby obtaining a S...

Abstract

The invention relates to a multilayer high-power nearly-spherical nano friction generator and an application thereof. The nearly-spherical nano friction generator includes a first electrode layer, an intermediate layer and a second electrode layer which are arranged in a laminated manner in an axial direction from inside to outside. An induction field is generated through friction between the first electrode layer and the intermediate layer or/and the intermediate layer and the second electrode layer. The first electrode layer and the second electrode layer are layered structures which include conductive layers. The intermediate layer is a layered structure which includes a high-molecular polymer layer. Voltage and current output electrodes of the nano friction generator are the conductive layers of the first electrode layer and the second electrode layer. The invention also provides a nano friction generator group which is obtained through serial or parallel connection of two or more than two nano friction generators. The invention also provides a child toy which includes the nano friction generator and a light-emitting diode.

Description

Technical field [0001] The invention relates to a friction generator, in particular to a nearly spherical nano friction generator composed of multiple layers. Background technique [0002] With the continuous improvement of modern living standards and the accelerating pace of life, self-generating equipment with convenient application and low dependence on the environment has appeared. Existing self-powered equipment usually uses the piezoelectric properties of the material. For example, in 2006, Professor Wang Zhonglin of the Georgia Institute of Technology in the United States and others successfully converted mechanical energy into electrical energy in the nanoscale range and developed the world's smallest generator-nano generator. The basic principle of the nanogenerator is: when nanowires (NWs) are dynamically stretched under external force, piezoelectric potential is generated in the nanowires, and the corresponding transient current flows at both ends to balance the Fermi...
