Graphene fiber

Abstract

The invention belongs to the technical field of graphene fiber, and particularly relates to graphene fiber. A wet spinning device comprises a box; a liquid storage box is fixedly connected into the inner wall of the box; a concentric-square-shaped plate is fixedly connected into a cavity of the liquid storage box, and the inner wall of the left side of the concentric-square-shaped plate is not fixedly connected with the end surface of the bottom of the liquid storage box; a pressing plate is slidably connected into the cavity of the liquid storage box, and the pressing plate is placed betweenthe concentric-square-shaped plate and the inner wall of the left side of the liquid storage box; uniformly arranged spray nozzles are fixedly connected into the inner wall of the concentric-square-shaped plate; and uniformly arranged cone-shaped tubes are fixedly connected into the inner wall of the liquid storage box. The graphene fiber is mainly used for solving the problems that in the processof spinning the graphene fiber by a current wet spinning device, the condition of yarn breaking can be frequently happen, the fiber can float in solidification fluid after being broken, and the broken fiber cannot follow a rotating roller to be wound on a winding reel; and meanwhile, the conveying and collecting process of the fiber cannot be affected due to the fact that the floating fiber can float on other fiber and is staggered with other fiber.

Description

technical field [0001] The invention belongs to the technical field of graphene fibers, in particular to a graphene fiber. Background technique [0002] Graphene is a carbon atom with sp 2 The hybrid orbitals form a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. Graphene is a two-dimensional material with a two-dimensional hexagonal honeycomb structure composed of carbon atoms in sp2 hybrid orbitals. Because graphene has a series of excellent physical properties such as high strength, high thermal conductivity, and high electrical conductivity, it has great application prospects in the field of materials, so it has become an international research hotspot in recent years. However, graphene is...

AI Technical Summary

Problems solved by technology

[0003] The wet spinning device in the prior art often breaks during the spinning process of graphene fibers. When the fibers are broken, they will float in the coagulation liquid, and the broken fibers cannot follow the rotation. The rod is wound on the winding, and the floating fibers will float to other fibers and interlace with other fibers, which will affect the fiber transportation and collection process. After the spinning is completed, the coagulation liquid needs to be released to collect the broken filaments, which will reduce the efficiency of graphene spinning

[0004] There are also some schemes about graphene fiber spinning in the prior art, such as patent number 201610474260.1, the patent name is a patent for graphene fibers, this technical scheme cannot solve the problem of fiber breakage in the process of making graphene fibers
