▎ 摘　　要

NOVELTY - The method comprises mixing the hydroxy-modified micro-nano thermal conductive material and the polymer base material, and preparing mixed solution to obtain a temperature-controlling fiber with integrated superconducting and refrigeration functions. USE - Method for preparing a temperature-controlled fiber with integrated superconductivity and refrigeration functions. ADVANTAGE - The method improves the heat transfer efficiency and improves the thermal conductivity. The hydroxy-modified boron nitride generates intermolecular hydrogen bonds with the polymer base material, which increases the loading content of the boron nitride in the fiber material, and has more uniform dispersion.
