Embodiment 2

[0037] On the basis of Example 1, different from Example 1, in the preparation method of polytetrafluoroethylene composite titanium dioxide sheet layer in the present example, adding mass fraction in PTFE emulsion is 15% TiO 2 The nanosheets are homogeneously mixed. After continuous treatment for 3 hours, the mass concentration of PM2.5 changed from 86 μg / m 3 Gradually decreased to 42μg / m 3 .

Embodiment 3

[0039] On the basis of Example 1, different from Example 1, in the preparation method of the polytetrafluoroethylene composite titanium dioxide sheet in the present example, adding mass fraction in PTFE emulsion is 20% TiO 2 The nanosheets are homogeneously mixed. After continuous treatment for 3 hours, the mass concentration of PM2.5 changed from 86 μg / m 3 Gradually decreased to 53μg / m 3 .

Embodiment 4

[0041] On the basis of Embodiment 1, the difference from Embodiment 1 is that the distance between the friction layer 1 and the two conductive layers 2 in this embodiment is 2.5mm. After continuous treatment for 3 hours, the mass concentration of PM2.5 changed from 86 μg / m 3 Gradually reduce to 50μg / m 3 .

Abstract

The invention discloses an environmental wind energy collection and air purification shutter which comprises blades, and each blade is of a TENG structure composed of a friction layer and conductive layers located on the two sides of the friction layer. The blades are provided with rectifiers used for converting alternating current generated by the TENG structure into direct current. The upper ends and the lower ends of the blades are provided with conductors used for being connected with the positive electrode and the negative electrode respectively. The two conductors are electrically connected; the rectifier is electrically connected with the two conductors. PM2.5 in the air is effectively removed in real time through the characteristics of high voltage and low current output by the TENG; the TENG and the flexible solar cell are combined to collect solar energy, so that the self-powered smart home can stably operate; passive wind energy detection is carried out through a good linear relation between the independent layer TENG structure and the wind speed.

Description

technical field [0001] The invention relates to a shutter, in particular to an environmental wind energy collection and air purification shutter. Background technique [0002] The triboelectric nanogenerator (TENG) uses the triboelectric effect to cause friction between two different electrode materials to generate a potential difference. In order to achieve the balance of the potential, the external circuit will transfer the flow of electrons. In terms of structure, friction nanogenerators include sliding friction nanogenerators, contact-separation friction nanogenerators, single-electrode friction nanogenerators, and induction friction nanogenerators. [0003] At present, the application of triboelectric nanogenerators in vibration sensors, pressure sensors, and ocean energy pickup has been announced, and there are reports on its home applications such as remote controls. However, there are no smart blinds, multi-functional composite energy harvesting systems combined wit...
