Problems solved by technology

[0003] Utilizing the negative charge characteristics of graphene oxide and graphene sheets, using electrostatic self-assembly technology, it can be alternately deposited with polymer cations to prepare graphene films. However, the conductivity and light transmittance of the film cannot be improved at the same time
This is because although single-layer graphene has excellent electrical properties, but for multi-layer graphene films, the better the conductivity, the greater the thickness of the graphene film, but the transmittance will decrease

Abstract

The invention discloses a method for printing a graphene / silver composite pattern by using a phthalocyanine nickel complex in a micro contact manner. The phthalocyanine nickel complex is prestox phthalocyanine nickel. The method comprises the following steps: by taking a dichloromethane solution of prestox phthalocyanine nickel as a printing agent of the micro contact printing, transferring a pattern of a PDMS seal to a polyimide substrate, further adsorbing and reducing graphene and silver, and finally obtaining delicate metal patterns on the substrate. By using the micro contact printing method, the graphene patterns can be printed on the surface of the polyimide substrate which is frequently used in the electronic industry, and a novel idea is provided for the micro contact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and particularly relates to the application of a nickel phthalocyanine complex as a green environmental protection ink in micro-contact printing. Background technique [0002] Surface micro-structuring technology is gradually showing important application value, especially micro-contact printing technology, which can be micro-patterned on a small scale, which is of great significance in many fields, especially in the field of modern electronic technology. At present, there are few microcontact printing inks to choose from, and the materials that can be printed on the surface are limited. A large number of materials cannot be prepared with surface patterns by microcontact printing. Therefore, it is of great significance to develop new and stable inks. [0003] Utilizing the negative charge characteristics of graphene oxide and graphene sheets, using electrostatic self-assembly technolo...
