Transmission electron microscopy analysis of octanethiol-coated Cu powders

In this study, microstructures of Cu powders coated with octanethiol were analyzed using (scanning) transmission electron microscopy. Moreover, aging process of the octanethiol-coated layer as time passes by was analyzed using the electron energy loss spectroscopy technique. The octanethiol layer coated on the surface of Cu powders was kept until it was exposed to air for around 30 days. As days passes by, the coating layer had been decomposed and then a Cu(2)O layer was formed on the surface of powders.This work was supported by the Technology Innovation Program (Project No. 100300209) funded by the Ministry of Knowledge Economy (MKE, South Korea)
