| titleOfInvention | Bismuth tungstate/tungsten oxide/polymer composite nanofiber membrane for high-energy ray protection and preparation method thereof |
| abstract | A bismuth tungstate/tungsten oxide/polymer composite nanofiber membrane for high-energy ray protection and a preparation method thereof belong to the technical field of preparation of ray protection materials. Firstly, preparing tungsten oxide nanorod seed crystals through hydrothermal synthesis, then mixing the tungsten oxide nanorod seed crystals with a high molecular solution to prepare an electrospinning precursor solution, obtaining a nanofiber membrane through an electrostatic spinning process, and obtaining the flexible heterogeneous composite nanofiber through a subsequent two-step hydrothermal process. Due to the physical and chemical properties of tungsten and bismuth tungsten oxide and the structural characteristics of the nano fibers, the obtained fiber film has high protection effect on X and gamma rays and can keep low density, the continuous nano fiber material solves the agglomeration problem of powder materials, the introduction of a non-conductive material avoids the interference of electromagnetic shielding effect on radio communication, and the fiber film can be used for photocatalytic degradation of organic pollutants after the life cycle of the fiber film serving as a high-energy ray protection material is finished, so that the fiber film is a novel nano material with good application prospect. |
