Embodiment 1

[0037] Divide 3.0×3.0cm 2 Nylon cloth is soaked in silver nanowire ethanol solution, then taken out and dried in a vacuum oven. Repeat this process until the silver nanowire loading is 0.9mg / cm 2AN cloth. The above-mentioned AN cloth was immersed in PDMS, and the AN cloth uniformly coated with PDMS was taken out and cured in an oven to obtain a PAN cloth with a coating thickness of 240 μm. FAS was mixed with isopropanol and then hydrolyzed by adding HCl solution to obtain a mixed solution of FAS isopropanol and water with a mass fraction of 1.26%. Put the PAN cloth into a plasma processor with a power of 200W for 5 minutes and then immerse it in the obtained FAS solution for 1 hour, take it out and dry it in an oven. figure 1 Schematic diagram of the preparation process. figure 2 It can be seen that the silver nanowires are uniformly distributed on the nylon cloth. The distance between the nanowires is about 300nm, which is much smaller than the wavelength (9μm) of infra...

Embodiment 2

[0039] Divide 3.0×3.0cm 2 Nylon cloth is soaked in silver nanowire ethanol solution, then taken out and dried in a vacuum oven. Repeat this process until the silver nanowire loading is 0.7mg / cm 2 AN cloth. The above-mentioned AN cloth was immersed in PDMS, and the AN cloth uniformly coated with PDMS was taken out and cured in an oven to obtain a PAN cloth with a coating thickness of 240 μm. FAS was mixed with isopropanol and then hydrolyzed by adding HCl solution to obtain a mixed solution of FAS isopropanol and water with a mass fraction of 1.26%. Put the PAN cloth into a plasma processor with a power of 200W for 5 minutes and then immerse it in the obtained FAS solution for 1 hour, take it out and dry it in an oven. The reduction of silver nanowire content will not only lead to uneven distribution of nanowires on the surface of nylon cloth, which will affect its thermal insulation performance; it will also increase the resistance of AN cloth, resulting in a decrease in its...

Embodiment 3

[0041] Divide 3.0×3.0cm 2 Nylon cloth is soaked in silver nanowire ethanol solution, then taken out and dried in a vacuum oven. Repeat this process until the silver nanowire loading is 1.5mg / cm 2 AN cloth. The above-mentioned AN cloth was immersed in PDMS, and the AN cloth uniformly coated with PDMS was taken out and cured in an oven to obtain a PAN cloth with a coating thickness of 240 μm. FAS was mixed with isopropanol and then hydrolyzed by adding HCl solution to obtain a mixed solution of FAS isopropanol and water with a mass fraction of 1.26%. Put the PAN cloth into a plasma processor with a power of 200W for 5 minutes and then immerse it in the obtained FAS solution for 1 hour, take it out and dry it in an oven. Excessive silver nanowire content has little effect on device performance, but increases the preparation time and the amount of silver nanowire, resulting in increased device cost.

Abstract

The invention relates to a personal energy managing device containing a fluoroalkyl silane hydrophobic surface layer and a production method and application of the personal energy managing device. The device is characterized in that silver nano wires AgNWs and polydimethyl siloxane (PDMS) sequentially wrap the surface of nylon cloth, and fluoroalkyl silane is grafted to the surface of the PDMS to form the device. The production method includes: soaking the nylon cloth wrapped by the silver nanowires (AN cloth) into the PDMS, and taking out and curing to obtain the AN cloth wrapped with the PDMS (PDMS / AN cloth); performing plasma treatment on the PDMS / AN cloth, soaking into an FAS solution, and drying to obtain the personal energy managing device. The personal energy managing device and the production method thereof have the advantages that the device is applicable to a friction nano power generator to convert mechanical energy into electric energy so as to power a small device and can be used as wearable heat managing equipment to keep a human body warm and provide a heating function; a simple dip-coating method is used to allow the fluoroalkyl silane to be grafted to the surface of the PMDS, and the output performance of the friction nano power generator is increased greatly.

Description

technical field [0001] The invention belongs to the field of energy management devices and their preparation and application, in particular to a personal energy management device with a fluorine-containing silane hydrophobic surface layer and its preparation and application. Background technique [0002] The rapid development of wearable devices brings a lot of convenience to people's life, but also brings great challenges to their energy supply. Although the power of a single wearable device is not high, its extensive use and continuity make it difficult for existing wearable devices to meet user requirements. In addition, the traditional battery energy also has many shortcomings such as poor safety and large environmental pollution. Therefore, continuous and efficient energy supply for wearable devices has become an urgent problem to be solved. [0003] The mechanical energy from the human body is highly sustainable and can be used in a wide range of activities, includin...
