CONDUCTIVE INK COMPOSITION FOR INKJET PRINTER, METHOD FOR FORMING METAL PATTERN BY INKJET PRINTING AND PRINTED CIRSUIT BOARD USING THE METHOD

摘要

conductive ink composition for ink jet printer according to the present invention, the metal nanoparticles; Co-solvent; Dispersing agents for maintaining the metal nano-particles in the ink in a stable dispersed state; Including a humectant for preventing clogging of the nozzle portion of the ink-jet printers, a viscosity of 0.5 to 40 mPa s range condition, Newtonian flow behavior conditions, to meet the range of conditions of a surface tension of 20 to 70mN / m characterized in. ; conductive metal by direct drawing method by a conventional energy-intensive and high cost of the optical patterning technology is environmentally-friendly and simple ink-jet printing process that can replace the production technique according to the method according to the invention may form a pattern. ; The ink composition of the present invention includes a metal nanoparticles dispersed stably in a high concentration, the low specific resistance can be obtained by a low temperature heat treatment, electric / electronic materials industry areas, as well as the application of a wide range of industries, including biotechnology industry is expected.
