Abstract

The invention discloses a micro-printing method by using a water soluble planar conjugated phthalocyanine porphyrin diad as micro-contact printing ink. The method specifically comprises the following steps: by using an aqueous solution of 5, 10, 15, 20-para amino phenyl porphyrin aluminum and hexacarboxyl aluminum phthalocyanine as a micro-contact printing agent, transferring an image of a PDMS (polydimethylsiloxane) stamp to a polytetrafluoroethylene substrate; and then obtaining an exquisite metallic silver pattern on the substrate by virtue of a method of adsorbing reduced silver. By using the aqueous solution of 5, 10, 15, 20-para amino phenyl porphyrin aluminum and hexacarboxyl aluminum phthalocyanine as the micro-contact printing agent to prepare metal patterns on the polytetrafluoroethylene surface frequently used in the electronic industry, the raw materials are easily available, and the method is low in cost and stable, has a huge potential in industrial application and provides a new concept for 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 water-soluble planar conjugated phthalocyanine porphyrin duplex 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] In order to further enrich the selection of microcontact printing inks and substrates and imp...
