Problems solved by technology

Current friction materials are usually limited to some conventional materials in the triboelectric series, but these materials are also subject to environmental factors (composition of gas, humidity), which affect the performance of TENG, especially humidity has a great influence on the performance of TENG, humidity increase, forming a water layer on the surface of the friction material, causing charge transfer or dissipation, and ultimately leading to a decrease in the output performance of the TENG

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0039] TENG is a nanogenerator based on triboelectrification and electrostatic induction coupling. Its basic principle is: when an external force is applied, two friction materials rub against each other, charge transfer occurs, and triboelectric charges are generated; after the deformation force is released, the two surfaces automatically Separated, due to the inclusion of an air layer in the middle, the charges on the two surfaces cannot be completely neutralized, thus forming a potential difference; in order to balance the potential difference, the opposite electric charge is induced on the electrode plate, and the external circuit will form an instantaneous current; when the external force is applied again, The potenti...

Abstract

The invention provides a friction nano-generator. A friction layer of the friction nano-generator is composed of a nano-composite film, wherein the nano-composite film is formed by compounding a high-molecular polymer and a metal organic framework. The nano-composite film is used as a friction layer of the friction nano-generator, the output performance of the friction nano-generator is improved along with increase of humidity. The friction nano-generator is particularly suitable for being applied to a high-humidity environment, and the actual application range of the friction nano-generator is greatly widened.

Description

technical field [0001] The invention relates to the field of generators, in particular to a friction nanometer generator. Background technique [0002] Due to environmental concerns such as the global energy crisis and global warming, sustainable and environmentally friendly harvesting of energy from nature has attracted extensive attention. Among energy harvesting technologies, triboelectric nanogenerators (TENG) have proven to be a cost-effective and simple technology to directly convert mechanical energy such as wind currents, ocean waves, and human motion into electrical energy. However, the low output performance of TENG greatly limits its large-scale commercial application. [0003] Recently, various methods to solve this problem have been reported one after another, for example, rational selection of friction materials, injection of charges, regulation of morphology and optimization of structures, etc. The charge density is the most effective way to improve the outp...
