Abstract

The invention discloses application of an alpha-cyclodextrin and rare-earth Dy complex composite solution in micro-contact printing. The alpha-cyclodextrin and rare-earth Dy complex solution serves as a printing agent for micro-contact printing, a pattern of a PDMS stamp is transferred to a carboxylic polyethylene substrate, and then a fine metal pattern is obtained on the substrate by adopting a chemical plating method. The alpha-cyclodextrin and rare-earth Dy complex composite solution serves as micro-contact printing ink to make the metal pattern on the bottom surface of the polyethylene substrate commonly used in the electronic industry, and a new thought is provided for the micro-contact printing industry.

Description

technical field [0001] The invention belongs to the field of modern electronic technology, and in particular relates to the application of γ-cyclodextrin and rare earth Dy complex as composite green 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 meet the requirements of the new generation of inks for environmental protection and human health, it is necessary to furt...
