Problems solved by technology

Because this method can deposit different materials in sequence, it can realize a variety of in-fiber devices, such as PN junctions, Schottky junctions, PIN junctions, ohmic contacts, etc. in fibers, but this process has certain limitations. The fiber length is limited, only centimeter to millimeter-scale fibers can be realized, and it is only suitable for materials that can be synthesized in the gas phase within the fiber, which has great restrictions on the materials used
[0006] The integration of functional fiber devices by doping materials with different electrical and optical properties in fibers is complex and limited, because a variety of materials are required to realize complex functions in fibers, including crystalline semiconductor materials, high-melting point alloys, Films, thermosetting polymers, etc., and these materials are often unable to achieve co-drawing with fiber materials. Due to the limitations of these materials and the requirements of micro-scale size control for micro-electronic devices, this method is used to fully integrate micro-electronic devices into fiber is not feasible
[0007] Chinese invention patent CN107564730A discloses a fluorescent fiber-shaped supercapacitor and its preparation. Oriented carbon nanotube fibers uniformly loaded with fluorescent components are used as electrodes, and the surfaces of the two fiber electrodes are uniformly coated with gel electrolyte and then intertwined to form a winding structure. Fluorescent supercapacitor fibers, but the preparation process is more complicated, and an external coating needs to be added
Chinese invention patent CN110227208A discloses a flexible fiber electrode coated with polyetheretherketone coating, which adopts the method of thermal softening and drawing, and performs co-drawing of polyetheretherketone preform and flexible filamentary conductive material to obtain a flexible fiber electrode. The flexible fiber electrode with polyether ether ketone as the core layer and polyether ether ketone as the cladding has the limitation that more other materials with thermal or electrical properties need to be added to achieve more complex functions, and the requirements for materials There will be more and more
