Abstract

The invention discloses a nanometer printing conductive ink composition and a preparation method thereof. The conductive ink composition is prepared from the following components according to the mass ratio: metal nanoparticles 20-50%, dispersant 1-8%, self-dispersing functional resin 15-35%, solvent 10-35%, thickener 1 -5%. The preparation method is as follows: after uniformly mixing the metal nano particles, dispersant, self-dispersing functional resin, solvent and thickener, grinding until the particle size is less than or equal to 100nm. The nano-printed conductive ink composition of the present invention uses a self-dispersing functional resin and a dispersant so that the nano-metal conductive particles are evenly distributed in the ink composition, thereby obtaining a conductive ink composition with strong adhesion and good conductivity. The initial volume resistance value of the formed metal film can be as low as 4 μΩ·cm.

Description

technical field [0001] The invention belongs to the field of conductive ink, and in particular relates to a nano-printed conductive ink composition and a preparation method and application thereof. Background technique [0002] With the development of semiconductor technology, the performance requirements of semiconductor components are getting higher and higher (electrodes, resistors, magnetic shielding components). Metal nanoparticles have excellent physical and sintering properties, and the progress of nanotechnology provides a strong support for the development of semiconductor technology. In the process of using nanomaterials, metal nanoparticles are usually dispersed in a specific organic carrier, and the composition is printed on the corresponding substrate (such as ceramic film, silicon, polymer film, glass or even paper) by printing technology. ), and then through its heat treatment (drying, firing, vacuum tempering), to achieve the functions of electrical componen...
