Abstract

The invention relates to a Janus nanobelt array film with a magneto-optical anisotropic conductive special structure and belongs to the technical field of nanomaterial preparation. The present invention comprises five steps: (1) precipitation method prepares the Fe coated with oleic acid 3 o 4 Nanocrystals; (2) Precipitation method to prepare Eu(BA) 3 phen; (3) prepare polymethyl methacrylate PMMA; (4) prepare spinning solution; (5) prepare magneto-optical anisotropic conductive {[Fe 3 o 4 / PMMA]@[Eu(BA) 3 phen / PMMA]} / / [PANI / PMMA] Janus nanoribbon array membrane with special structure, using special two-strand parallel spinning spinneret, aluminum drum as the receiving device, prepared by electrospinning technology. The prepared Janus nanoribbon array film with special structure has three functions of high anisotropy conduction-magnetism-luminescence at the same time. The method of the invention is simple and easy, and can be produced in batches.

Description

technical field [0001] The invention relates to the technical field of nanometer material preparation, in particular to a Janus nanobelt array film with a special structure of magneto-optical anisotropy and conductivity. Background technique [0002] Anisotropic conductive film is a new type of interconnection material for electronic components. It has conductivity in one direction and insulation in other directions. It has been widely used in electronic packaging, chip fixing and electrode bonding, etc., causing people's attention. [0003] 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 m...
