Abstract

The invention relates to a magnetic green fluorescent bianisotropic electric-conductive flexible composite film and a preparation method thereof, and belongs to the technical field of preparation of nanometer materials. The preparation method comprises: (1) preparing a Tb(BA)3(phen) coordination compound through a precipitation method; (2) preparing an oleic acid coated Fe3O4 nano-crystal througha precipitation method; (3) preparing polymethyl methacrylate PMMA; (4) preparing a spinning solution; (5) preparing a [Tb(BA)3phen / PMMA] / / [PANI / Fe3O4 / PMMA] anisotropic electric-conductive magnetic green fluorescent Janus nano-belt array film; and (6) preparing a magnetic green fluorescent bianisotropic electric-conductive flexible composite film. According to the present invention, the prepared flexible composite film has good magnetic green fluorescent bianisotropic electric-conductive characteristic; the method is simple and easy to perform, and is suitable for batch production; and the novel nanometer material has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of nanometer material preparation, in particular to a magnetic green fluorescent bi-anisotropic conductive flexible composite film and a preparation method thereof. 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 and other fields. Classified according to its conductive direction, it can be divided into the following two categories: Type I anisotropic conductive film: this anisotropic conductive film conducts electricity along the thickness direction of the film and insulates along the direction of the film surface. The preparation technology is now very mature and has been widely used in electronic equipment; Type II anisotropic conductive film: this anisotropic conductive film...
