▎ 摘　　要

NOVELTY - The method involves performing primary twisting on the initial single fiber obtained by wet spinning or electrostatic spinning to obtain a primary twisted fiber bundle, using a clockwise twisting method. The clockwise secondary twisting is performed using multiple strands of the primary twisted fiber bundle to obtain multiple strands of L-shaped twisted fiber bundle. The counterclockwise secondary twist is performed on the multi-strand L-shaped twisted fiber bundle to obtain a multi-strand R-shaped twisted fiber bundle or a second-twisted fiber bundle. A conductive material is added to form the anisotropic twisted fiber bundle, in the second twisting process. The polyvinyl alcohol/phosphoric acid electrolyte is added during the second twisting. The anisotropic twisted fiber bundle capable of storing electric charges is obtained after reduction and post-treatment. USE - Method for preparing anisotropic twisted fiber bundles used as energy storage device such as carbon nanotube-based super-capacitor and lithium ion battery energy storage device or used for anisotropic liquid transportation for water collection, mist collection, and liquid adsorption and diffusion (all claimed). ADVANTAGE - The anisotropic twisted fiber bundle can realize the integration of multiple kinds of materials and multiple functions, has structure and performance anisotropy and high strength and flexibility, and the size of the fiber is controllable, can be randomly bent and woven.
