Abstract

The invention discloses a preparation method of an anisotropic conductive macromolecule composite thin film. The preparation method includes following steps: 1), uniformly adding carbon nanotubes coated with nano ferroferric oxide magnetic particles into a polyaniline-N-methylpyrrolidinone solution according to a mass percentage of 0.5-15%, and stirring well to obtain a carbon nanotube / ferroferric oxide-polyaniline solution; 2), adding the nanotube / ferroferric oxide-polyaniline solution into a polyurethane solution, and stirring well to obtain a carbon nanotube / ferroferric oxide-polyaniline-polyurethane solution; 3), dropping the carbon nanotube / ferroferric oxide-polyaniline-polyurethane solution onto a glass sheet for casting to form a thin film, putting the obtained thin film in a magnetic field for magnetic orientation, and drying at high temperature to obtain the anisotropic conductive macromolecule composite thin film. The preparation method is simple and easy to implement, high in result repeatability and easy to control.

Description

technical field [0001] The invention belongs to the field of preparation technology and special performance of nano-composite material composite film, specifically, the invention relates to a preparation method of anisotropic conductive polymer composite film. Background technique [0002] Anisotropic conductive polymer films have become a research hotspot in many electronic fields due to their different conductivity in different directions. At present, most of the work is to prepare conductive films or conductive adhesives that are conductive in the Z-axis and non-conductive in the XY-axis, and their conductivity is also low. [0003] Although conductive polymer films have excellent properties such as lightness and bending resistance, some conductive polymer films will break when soaked in acid. However, the conductive polymer film with acid corrosion resistance has not been reported yet. Therefore, how to control the conductive polymer film in the acid-resistant region t...
