Abstract

The invention discloses PEDOT conductive ink photodimerizable by ultraviolet light. The conductive ink comprises the following components by weight: 1-3% of PEDOT / PVMA conductive powder, 1-10% of a humectant, 1-10% of a doping agent, 0.1-5% of a surfactant, 1-10% of a pH regulator and 63-98% of a solvent. The conductive ink is prepared by mixing the components. The conductive ink solves the problems that the traditional PEDOT ink has bad water resistance and weatherability, and complex preparation technology; the conductive ink has the advantages of low cost, simple preparation method, good water resistance and weatherability, good conductivity, etc.

Description

technical field [0001] The invention relates to the technical field of conductive materials, in particular to a method for dispersing PEDOT with UV dimerizable PVMA and making conductive ink. Background technique [0002] Inkjet printing technology (inkjet printing) is a printing technology that prints continuous tiny ink droplets onto a substrate to form a thin film in a non-contact manner under computer control. With the development of science and technology, functional inks have replaced traditional dye inks and pigment inks and have been successfully applied to electronic products through inkjet printing technology, which has attracted widespread attention in the field of functional material patterning and optoelectronic device applications. . [0003] With the continuous increase of people's multi-functional demand for electronic products, conductive ink, as one of the key factors of inkjet printing technology, has also developed rapidly. In recent years, nano-metal pa...
