Abstract

The invention discloses a conductive micro-nanometer fiber stranded wire based on solvent-free electrospinning and a preparing method thereof. The conductive micro-nanometer fiber stranded wire comprises a photocuring material template stranded wire and a conductive macromolecule layer. The photocuring material template stranded wire is formed by winding micro-nanometer fiber cured by solvent-free electrospinning ultraviolet light. The conductive macromolecule layer is manufactured through an in-situ polymerization method and comprises conductive macromolecule layer bodies permeating into the template stranded wire and wrapping the template stranded wire. According to the conductive micro-nanometer fiber stranded wire, conductivity of the fiber stranded wire is further improved while excellent stretchability is kept, organic solvent does not need to be added in the electrostatic spun yarn preparing process, the preparing process is safer and more environmentally friendly, and the stranded wire is suitable for large-scale production.

Description

technical field [0001] The invention relates to a conductive micro-nano fiber stranded wire based on solvent-free electrospinning and a preparation method thereof, belonging to the field of nanomaterial preparation. Background technique [0002] Electrospinning technology is a simple and effective method for preparing micro / nano fibers. Nanofibers prepared by electrospinning technology can be made into more abundant structures such as stranded wires to expand its application range. However, in the traditional electrospinning technology, most of the organic solvents will be used in the spinning process, resulting in a great waste of resources and environmental pollution, and even some organic solvents are toxic, which will damage human health. The solvent-free spinning technology does not require a solvent in the spinning process, thus solving the disadvantages of traditional solvent spinning that pollutes the environment. The current solvent-free spinning includes melt spin...
