Abstract

The invention discloses a greenhouse film-based frictional nanogenerator for collecting raindrops and a preparation method thereof. The substrate and the conductive polymer are functionally modified, and strong adhesion between the two can be achieved by simple spin coating, brush coating, etc., and the thickness is thin enough to meet the transparency requirements, thus successfully preparing the film lower electrode. In addition, a very thin copper tape was pasted on the superhydrophobic surface of the superhydrophobic modified film to construct the upper electrode of the film, and to construct a frictional device with high output efficiency based on the superhydrophobic modified greenhouse film and the two-electrode working mode. Nanogenerator: On the premise of meeting the requirements of transparency as a whole, a triboelectric nanogenerator with high output performance is prepared to realize the collection of raindrop energy in the environment. Compared with the original film, the output performance of the triboelectric nanogenerator constructed by using the superhydrophobic modified film in the present invention is greatly improved, and the construction process of the triboelectric nanogenerator is simple and easy to realize.

Description

technical field [0001] The invention relates to a triboelectric nanogenerator based on the principles of triboelectric electrification and electrostatic induction and a preparation method thereof, in particular to the use of a greenhouse film as a triboelectric layer material, and a novel double-electrode structure to construct a triboelectric nanogenerator and its preparation Methods for raindrop energy collection in the environment. Background technique [0002] Greenhouse cultivation is one of the typical forms of agricultural production and consists of a transparent medium that transmits short-wavelength solar radiation. Covering materials, skeletons, cultivation facilities and technical equipment required to control the microclimate inside the greenhouse are the essential elements that make up the greenhouse. Among them, the materials covering the outside of the greenhouse frame are the most important components of the greenhouse, usually including plastic films, glass...
