摘要：Copper-containingelectronic pastes with the merits of low costand high conductivity have been actively investigated for preparingconductive electrodes for printable electronics. However, oxidationof copper electrodes in the ambient atmosphere deteriorates devicesand restricts their practical applications. Here, we designed an artificialglass nanobarrier layer on copper spheres to improve the antioxidationproperties by blocking further oxidation. Specifically, a non-aqueoussol-gel method was applied to synthesize zinc borosilicateglass nanolayer-coated copper spheres with various diameters from200 nm to 10 & mu;m with zinc borosilicate glass nanolayer (Cu@ZBS).The Cu@ZBS-based copper pastes were screen printed on the siliconwafer and low-temperature co-fired ceramic (LTCC), demonstrating low-sheetresistance (11 m & omega;/), strong adhesion, and long-termstability. Our study blazes the trail of applicating reliable Cu@glasscore-shell materials to fabricating conductive electrodes inprintable electronic devices.
