A preparation method and application technology of polyionic liquid functionalized nanofibers

Abstract

The present invention discloses a preparation method and an application technology of poly ion liquid functionalized nanometer fibers. The preparation method comprises: (1) preparing a poly ion liquid; (2) mixing and dissolving the poly ion liquid and a substrate material in a solvent to form a mixed solution; and (3) adopting an electrostatic spinning method to spin the mixed solution into poly ion liquid functionalized nanometer fibers. The application technology comprises: placing the poly ion liquid functionalized nanometer fibers inside the substrate fabric or on the surface of the substrate fabric to prepare anti-radiation equipment so as to absorb or filter radiation hazard of I<131>. According to the present invention, according to the absorption principle and the electrostatic spinning technology, the specific poly ion liquid is utilized to design and prepare the poly ion liquid functionalized nanometer fibers with the efficient absorption effect and a series of the anti-radiation equipment so as to efficiently absorb, isolate and remove I<131> in the environment, and provide advantages of high absorption capacity, good absorption effect, effective radiation hazard reducing and the like.

Description

technical field [0001] The invention relates to the technical field of anti-radiation materials, in particular to an iodine-131 (I 131 ) of polyionic liquid functionalized nanofibrous materials and their applications. Background technique [0002] I 131 It mainly comes from the products of nuclear fission, including radioactive fallout from atmospheric nuclear tests, nuclear power plant operation and major nuclear accidents. Production and nuclear medicine applications are the main sources of radioactive iodine pollution to the environment and thyroid doses to humans. [0003] I 131 There are generally two ways to damage the human body: one is the external release type, and the other is the absorption type. 131 Produce nuclear radiation outside the human body and act on the human body. Compared with the absorption type, this method is less harmful. Generally, it is enough to stay away from the radiation source, that is, these isotopes. As long as it does not absorb a larg...

[0003] I 131 There are generally two ways to damage the human body: one is the external release type, and the other is the absorption type. 131 Produce nuclear radiation outside the human body and act on the human body. Compared with the absorption type, this method is less harmful. Generally, it is enough to stay away from the radiation source, that is, these isotopes. As long as it does not absorb a large dose of radiation in a short period of time, it is generally not It will have too much impact on the human body
