건식법으로 1-Octanethiol 코팅한 Cu 나노 분말 잉크의 잉크젯 인쇄 기술 적용

Abstract

Inkjet printing was successfully done using Cu nano powder ink after these Cu nano powders were dry-coated with 1-octanethiol for oxidation prevention. 1-octanethiol, which is Self-Assembled Multi-layers (SAMs), was coated approximately 10-nm thick on the surface of Cu nano powders. 1-Octanol, which has the same chain length as that for 1-octanethiol, was used as a solvent to make the ink for inkjet printing. As a result,the fabricated ink was dispersed for about 4 weeks, and after printing and heat treatment at 350oC for 4 hours, the resistivity for the printed pattern was measured to be 1.15×10^(−5)Ω · cm.
