Embodiment 1

[0032] A preparation method for fully recyclable frictional generators. The preparation method first uses water-soluble organic materials to prepare a functional film layer, forms an electrode layer on one side of the functional film layer by evaporation, and then utilizes the water-soluble organic material to form an electrode layer. The base layer is prepared by using a non-toxic organic material, and then the base layer and the functional film layer coated with the electrode layer are assembled. When assembling, the surface of the functional film that is not coated with the electrode layer is facing outward, and finally the electrode layer is connected to the wire. , to prepare a completely recyclable friction generator.

[0033] The thickness of the functional film layer is 50 microns, the thickness of the base layer is 200 microns, and the thickness of the electrode layer is 200 nanometers.

[0034] Described preparation method specifically comprises the following steps: ...

Abstract

The invention relates to a fully-recyclable friction generator and a preparation method thereof. The fully-recyclable friction generator comprises a base portion, an electrode portion and a function film layer portion. The function film layer, the metal electrode layer and the base layer are made of a water-soluble material, and thus the whole device can be fully dissolved; and a solution obtained after dissolution can form films, and thus the purpose of being fully recyclable is achieved. Before cyclic utilization, the friction generator can work normally; and after cyclic utilization, the output and dissolution time performances and the like of the generator are not reduced, and the generator can still play a normal role, including collecting mechanical energy in living environment and serving as a motion sensor for monitoring human motion and mechanical vibration and the like. The fully-recyclable friction generator has the advantages of easy preparation, low cost, non-poisonous and harmless dissolution products and zero waste and the like; and the fully-recyclable friction generator has a great prospect in future practical application and after-service processing.

Description

technical field [0001] The invention mainly belongs to the fields of micro-nano energy and circular economy, and specifically relates to a completely recyclable friction generator and a preparation method thereof. Background technique [0002] The development of modern society is increasingly inseparable from the rapid development of a large number of electronic devices. Miniaturization, low energy consumption, intelligence, and multi-function are some trends in the development of electronic devices, and power supply for these electronic devices has become a hot research field. Harvesting energy from the environment to power these electronic devices becomes particularly attractive against the background of ever-lower power consumption of electronic devices. This is also the background for the self-driving system concept. Since the triboelectric nanogenerator was invented in 2012, it has developed rapidly due to its high efficiency, low cost, wide range of material options,...
