Abstract

The invention relates to a green light-emitting electromagnetic three-function double-layer composite nanofiber membrane and a preparation method thereof, and belongs to the technical field of preparation of nanomaterials. The preparation method comprises the following four steps: (1) preparing oleic acid-coated Fe3O4 nanocrystals by a precipitation method; (2) preparing a Tb(TTA)3(TPPO)2 complexe by a precipitation method; (3) preparing a spinning fluid; (4) preparing a [Tb(TTA)3(TPPO)2 / PVP] / [PANI / Fe3O4 / PAN] green light-emitting electromagnetic three-function double-layer composite nanofiber membrane by a uniaxial electrospinning technology. The prepared green light-emitting electromagnetic three-function double-layer composite nanofiber membrane has good green light-emitting, conductive and electromagnetic functions at the same time. The preparation method is simple and feasible; the green light-emitting electromagnetic three-function double-layer composite nanofiber membrane can be produced in batches; the novel nanostructured material has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a green luminescent electromagnetic three-functional two-layer composite nanofiber membrane and a preparation method thereof. Background technique [0002] The application range of single-functional nanomaterials is limited, while the application range of bifunctional or multifunctional nanomaterials is wider, and these materials are more distinctive and attractive. Therefore, multifunctional nanomaterials are highly concerned by researchers. With the development of nanotechnology, nanomaterials have developed from a single function, such as having luminescent properties, conductivity or magnetism, to a dual function and multifunctional direction, such as having magneto-optical, photoelectric or electromagnetic dual functions, and photoelectromagnetic triple functions. Realizing dual or trifunctional functions on a nanostructured material is of great significance...
