Description

[0001] FIBER FOR GENERATING ELECTRICITY

[0002] Technical Field

[0003] The present invention relates to fibers which exhibit triboelectric property, can generate electricity from incoming regular or irregular motions and in which a low-dimensional material is integrated in order to generate electricity.

[0004] Background of the Invention

[0005] There is no production of long-length polymer fibers with low-dimensional material integrated therein by thermal fiber drawing method in the current technique. This situation leads to the need for fibers with long dimensions. On the other hand, existing polymer fibers have low electricity generation performance due to physical effects. For this reason, there is also a need to enhance the production performance of fibers. Fibers with enhanced production performance will also increase the possibilities of practical use.

[0006] The United States patent document no. US2022255464, an application included in the state of the art, discloses triboelectric fibers. In the invention subject to the said United States patent document, the properties of triboelectric fibers and the production methods of the fibers are described. In one example, a method of production of a fiber for generating energy using the triboelectric effect includes forming a preform tube, heating the preform tube in a furnace, feeding a wire through the preform tube and the furnace during the heating, and pulling the wire through the furnace to form a fiber. It can be relied upon to manufacture fibers long enough for industrial-scale textile manufacturing, including for use with industrial-scale looms. In one example, forming the preform tube can include providing a polypropylene tube and wrapping the polypropylene tube with a housing layer of amorphous film, such as acrylic film. The acrylic film can be relied upon to maintain the form and integrity of the polypropylene as the wire is pulled, and the acrylic film can be easily removed after the pulling.

[0007] Summary of the Invention

[0008] An object of the present invention is to realize fibers in which a low-dimensional material is integrated in order to generate electricity.

[0009] Another object of the present invention is to produce fibers with long lengths via thermal fiber drawing method by integrating low-dimensional materials into polymer fibers.

[0010] A further object of the present invention is to realize a fiber which can generate electricity by means of its physical movement.

[0011] Detailed Description of the Invention

[0012] “Fiber for Generating Electricity” realized to fulfd the objectives of the present invention is shown in the figures attached, in which:

[0013] Figure 1 shows the cross-sectional area of the inventive electric-generating fiber.

[0014] Figure 2 is a view of another cross-sectional area of the inventive electricgenerating fiber.

[0015] Figure 3 is a perspective view of the inventive electric-generating fiber.

[0016] The components illustrated in the figures are individually numbered, where the numbers refer to the following:

[0017] 1. Fiber

[0018] 2. First layer 3. Second layer

[0019] 4. Third layer

[0020] The inventive fiber (1) which exhibits triboelectric property, can generate electricity from incoming regular or irregular motions and in which a low- dimensional material is integrated in order to generate electricity comprises at least one first layer (2) which has a form of long, thin wire shape filled therein and has conductive property; a second layer (3) which surrounds the first layer (2) and is embedded with a low-dimensional material with electricity-generating property; and at least one third layer (4) which supports the production phase, acts as protection, is removed before the application phase and surrounds the second layer (3).

[0021] The first layer (2) included in the inventive fiber (1) is the innermost core layer in which carbon particles are embedded. The first layer (2) is made of a CPE (conductive polyethylene) polymer that can conduct electricity and is configured to enable the generated electric current to be conducted.

[0022] The second layer (3) included in the inventive fiber (1) is located between the first layer and the third layer (4) and is in contact with both layers. The second layer (3) is made of poly vinylidene fluoride (PVDF) polymer exhibiting triboelectric property that has the capacity to generate an electric current wherein at least one of the following low-dimensional materials is integrated in the form of 2- dimensional materials such as transition metal carbides with a thickness of a few atoms, transition metal nitrides, transition metal dichalcogens and graphene, graphene oxide, and / or O-dimensional nanoparticle- shaped materials such as silver, gold, zinc oxide, and / or 1 -dimensional nanowire materials such as zinc oxide and silver. In the second layer (3), low-dimensional materials are distributed homogeneously by being integrated viachemical methods . The third layer (4) included in the inventive fiber (1) has mechanical properties that help to maintain the integrity of the structure during fiber drawing and is made of at least one of polycarbonate (PC), poly ethersulfone (PES) or similar polymers that can be converted into fiber form by thermal processes. The third layer (4) is the outermost layer used in order to maintain the stability during fiber production.

[0023] During the production of the inventive fiber (1), a preform is obtained by producing the first, the second and the third layers (2, 3, 4) separately or together and then the production of fibers with long lengths is performed by combining the preform by thermal fiber drawing method. The obtained fibers (1) exhibit triboelectric property and can generate electricity from incoming regular or irregular motions. The produced fibers (1) are used in systems that can generate electricity from physical movements and as self-propelled sensors. The said fibers (1) can also be used in combination with standard signal sensing devices and a device that performs a physical tapping motion.

[0024] Within these basic concepts; it is possible to develop various embodiments of the inventive “Fiber for Generating Electricity (1)”; the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
