Embodiment 1

[0031] figure 1 It is a structural schematic diagram of the integrated triboelectric nanogenerator of this embodiment. Such as figure 1 As shown, it includes a power generation component with a porous structure, the power generation component includes a flexible polymer material 2 and a porous conductive framework 1, and the flexible polymer material 2 is wrapped on the porous conductive framework 2 to form a flexible porous structure. When the external force deforms the power generation component, or the polymer on the upper surface is in contact with the external object, the charge separation is caused by the contact friction between the composite porous conductive framework / polymer material, and the separated charge is transferred through the porous conductive framework. The potential difference between the two electrodes (or between the upper and lower surfaces) is caused to generate a current, and the output power is increased through the porous conductive skeleton and t...

Embodiment 2

[0045] image 3 It is a schematic structural diagram and a schematic diagram of the power generation principle of the generator provided in this embodiment. On the basis of Embodiment 1, the generator may also include a first electrode layer and a second electrode layer 5, which are arranged on two different surfaces of the power generation component; As shown in the figure, it can be selected to be arranged on the upper and lower surfaces of the power generation component. When the external force acts to deform the power generation component, a current is generated between the first electrode layer and the second electrode layer.

[0046] The first electrode layer and the second electrode layer 5 can use commonly used electrode materials, can be obtained by depositing conductive materials on the power generation components, or can be realized by directly pasting conductive sheets on the outside of the power generation components.

[0047] Taking copper foil as the first elect...

Embodiment 3

[0051] Unlike the generator in Embodiment 2 that includes two electrode layers, in this embodiment it may also include only one electrode layer, that is, the generator also includes a third electrode layer, and the third electrode layer is arranged on the surface of the power generation component. During the process of deformation of the power generation component by the action of external force, or the process of contacting and separating the external object from the third electrode layer, a current is generated between the third electrode layer and the equipotential.

[0052] The equipotential in this embodiment may be a ground potential, an equipotential circuit or a metal.

Abstract

The invention belongs to the nano-power generation field and discloses an integrated friction nano-generator. A porous conductive frame which is of a porous structure is formed in a polymer material which is of a porous structure, so that a flexible power generation component can be formed; when an external force acts on the power generation component and makes the power generation component deform, or when the polymer on the upper surface of the power generation component contacts or leaves an external object, charge separation is induced by contact friction between the composite porous conductive frame and the polymer material; separated charges are transferred through the porous conductive frame, as a result, electric potentials of two electrodes, or electric potentials of the upper surface and lower surface of the power generation component are different, and current can be generated; and output power is increased by the porous structures of the porous conductive frame and the polymer material, and therefore, mechanical movement such as shaking, tapping, friction, vibration, and rubbing, can be transformed into electric energy.

Description

technical field [0001] The invention relates to the field of nano power generation, in particular to an integrated friction nano generator for converting mechanical energy into electrical energy and a preparation method thereof. Background technique [0002] The energy crisis is a prominent problem facing modern society, but many mechanical energies that seem to be weak but actually have a huge amount are mostly ignored and not utilized. At present, in the prior art, friction generators have been successfully prepared by using the principles of friction electrification and electrostatic induction. Such friction generators can convert mechanical energy into electrical energy, especially in the collection and transformation of low-frequency energy such as human activities. Advantage. [0003] However, in the prior art, the upper and lower electrodes of the above-mentioned friction generators are usually on different planes respectively, the structure is complicated, and a lot...
