Abstract
A magnetic response fiber material and a preparation method and an application thereof are provided, which relates to the field of oil-water separation materials. The preparation method includes: mixing a fiber-forming polymer, a primary solvent, a secondary solvent and magnetic nanoparticles to form a uniform spinning solution, where the fiber-forming polymer includes at least one of polyethylene, polypropylene and polymethylpentene; spinning the spinning solution by a spinning process to obtain the magnetic response fiber material. The prepared magnetic response fiber material has the advantages of high oil absorption speed, high oil absorption capacity and high separation efficiency. Magnetic nanoparticles have a high load, which can not only be driven by magnetic force to absorb oil floating on water surface, but also be driven to an underwater oil pollution position to absorb oil, and can be applied to water purification in oil-polluted areas that cannot be reached by manual processing.
