Embodiment 1

[0038] Preparation of MOF-based plant leaf triboelectric nanogenerators:

[0039] The leaves were washed alternately with ultrapure water and ethanol for 10 s. Weigh 100mg of copper acetate and dissolve it in 100mL of pure ethanol to prepare a concentration of 5mM copper acetate solution, weigh 24mg of tetrafluorophthalic acid and dissolve it in 100mL of pure ethanol to prepare a concentration of 1mM tetrafluorophthalic acid solution, weigh Dissolve 11.2mg of triethylenediamine in 100mL of pure ethanol to prepare a solution of triethylenediamine with a concentration of 1mM. 50 mL of tetrafluorophthalic acid solution and 50 mL of triethylenediamine solution were mixed respectively to obtain 100 mL of tetrafluorophthalic acid / triethylenediamine mixed solution with a concentration of 0.5 mM.

[0040] Subsequently, if figure 1As shown, put 100mL of 5mM copper acetate solution, 0.5mM tetrafluorophthalic acid / triethylenediamine mixed solution and pure ethanol into the watering can...

Abstract

The invention discloses a preparation method and application of an MOF-based plant leaf friction nano-generator. The preparation method comprises the following steps: washing a substrate clean, preparing a copper acetate solution, and mixing a tetrafluorophthalic acid solution and a triethylene diamine solution to obtain a mixed solution A; spraying a copper acetate solution, the mixed solution A and absolute ethyl alcohol on the surface of a substrate, wherein the copper acetate solution, the absolute ethyl alcohol, the mixed solution A and the absolute ethyl alcohol are sequentially sprayed; after each solution is sprayed, using a fan with a heating function for evaporating absolute ethyl alcohol on the surface of the substrate; and repeatedly spraying for a plurality of times to obtain the MOF-based plant leaf friction nano-generator. The nano-generator has the advantages of being easy to prepare, good in biocompatibility, high in sensitivity and free of batteries, can stably work for a long time, and is an excellent substitute of a traditional wind speed sensor.

Description

technical field [0001] The invention relates to a frictional nanogenerator in the field of new energy and nanotechnology, in particular to a preparation method and application of a MOF-based plant leaf frictional nanogenerator. Background technique [0002] The rapid rise of triboelectric nanogenerators (TENG) has promoted the emergence of new design concepts such as battery-free, self-powered, and self-sensing in the field of wearable electronics. At present, the commonly used triboelectric layer materials are mainly polymers, especially some polymers with good flexibility and strong electron donating ability, including polytetrafluoroethylene (PTFE), polydimethylsiloxane (PDMS), polyimide Amine (PI), etc., can be used to develop blue energy, in vivo health monitoring devices, battery-free environmental monitoring devices, etc. Therefore, there are a large number of reports based on triboelectric nanogenerators for energy harvesting and environmental sensing. [0003] As ...
