Abstract

The invention discloses a liquid drop flow power generation device and a manufacturing method thereof. The device comprises a slide, electrodes, a flow power generation layer, a hydrophobic layer and a surface potential modification layer. The manufacturing method particularly comprises steps: two mutually-non interactive electrodes are formed on the insulated slide through a deposition or printing mode; a layer of flow power generation layer formed by solid micro nano powder is formed between the two electrodes through a deposition or printing mode; after activating treatment, surface treatment is then carried out on a specified flow power generation layer area, and the hydrophobic layer and / or the surface potential modification layer are / is formed; and a liquid drop drops on the flow power generation layer of the device, the liquid drop flows in the flow power generation layer in a directed mode, and thus, a potential difference and current are generated between the two electrodes in the flow radial direction. According to the manufacturing method provided by the invention, on-demand modification is carried out on the flow power generation layer, hydrophobicity or a feature of enabling the surface potential to be turned is realized, and the directions and the magnitudes of voltage and current outputted by the power generation devices can thus be changed.

Description

technical field [0001] The invention belongs to the field of new energy power generation equipment, and more specifically relates to a droplet flow power generation device and a preparation method thereof. Background technique [0002] With the continuous reduction of traditional non-renewable energy sources such as fossil fuels, the energy crisis is intensifying, and the environmental problems caused by the combustion of fossil fuels are becoming more and more prominent. Therefore, the development and utilization of renewable clean energy has become an important issue for all mankind. development focus. [0003] When a droplet enters the porous material, it will flow inside the porous material under the action of capillary force. During this process, a potential difference and current can be generated in the direction of flow, and through the evaporation of the liquid, it can provide a continuous flow of water when the liquid is sufficient. Capillary force for power genera...
