A mxene-based weavable functional composite fiber and a preparation method thereof

Abstract

The application provides a MXene-based braiding functional composite fiber and a preparation method thereof, and belongs to the technical field of functional fiber materials. The MXene-based braiding functional composite fiber provided by the application can realize the synergistic improvement of braiding and functionality. The TPU macromolecular chain serves as a flexible skeleton, promotes fiber forming and macro flexibility. The few-layer MXene nanosheet uniformly dispersed in the TPU macromolecular chain builds an initial conductive network in the core layer. The PPy skin layer grown through in-situ polymerization not only contributes to high electrochemical activity and increases the interlayer spacing of the MXene, but also forms a synergistic effect with the MXene to improve the electrochemical performance, and builds a three-dimensional synergistic conductive structure in the fiber, which is connected from inside to outside and stable. The structure ensures that the conductive and functional network of the fiber is not easily damaged when the fiber bears the mechanical action of textile processing, so that the mechanical durability and electrochemical performance are achieved.
