Abstract
The invention relates to a magneto-optical anisotropic conductive special structure Janus nanobelt array film, which belongs to the technical field of nanometer material preparation. The preparation method comprises the following five steps of: (1) preparing the oleic acid-coated Fe3O4 nano-crystal by a precipitation method; (2) preparing Eu (BA) 3phen by precipitation method; (3) preparing polymethyl methacrylate PMMA; (4) preparing spinning solution; (5) preparing magneto-optical anisotropic conductive {[Fe3O4 / PMMA]@[Eu(BA) 3phen / PMMA] } / / [PANI / PMMA] Janus nanoribbon arrays with special structure, adopting special two-strand parallel spinning spinneret, aluminum rotary drum as receiving device and using electrostatic spinning technology. The prepared special structure Janus nanobelt array film has three functions of high anisotropic conductive-magnetism-luminescence. The preparation method is simple and feasible, and can be produced in batch.
Description
Technical field [0001] The invention relates to the technical field of nano material preparation, in particular to a Janus nanobelt array film with a special structure of magneto-optical anisotropy conductive. Background technique [0002] Anisotropic conductive film is a new type of electronic component interconnection material. It has conductivity in one direction and insulation in other directions. It has been widely used in electronic packaging, chip fixing, electrode bonding and other fields, causing It is highly valued by people. [0003] The application range of single-functional nanomaterials is limited, while the application range of dual-functional or multifunctional nanomaterials is wider. Such 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 light-emitting properties, conductivity or magnetism, ...
