Abstract
A novel method of carbonaceous coating on the surface of copper particles was developed through a chemical vapor deposition (CVD) process to prevent the oxidation of copper nanoparticles (CNPs). The types of poly(vinyl pyrrolidone) (PVP) used were K-12 (M-W 3,500) and K-30 (M-W 45,000). The amounts of PVP used ranged from 10 to 50 wt %. Additionally, processing temperatures of 900 and 875 degrees C were tested and compared. The optimum CVD process conditions for the carbonaceous coating were as follows: 875 degrees C processing temperature, 50wt% K12 PVP solution, and gas conditions of Ar : H-2 = 1 : 1. The resistivity change in the fabricated copper pattern was confirmed that the initial resistivity value of the ink with a mixing ratio of carbonaceous-coated CNPs to 1-octanethiol-coated CNPs of 4 : 6 (w/w) maintained its initial resistivity value of 2.93 x 10(-7) Omega.m % m for more than 210 days.
