The oxidation state of a buried copper surface under a phenolic resin insulating layer was investigated by nondestructive anal. methods using conversion electron yield X-ray absorption fine structure (CEY-XAFS) and hard XPS (HAXPES). The formation of Cu2O and CuO during heat treatment at 180°C in air and the formation of Cu(OH)2 and CuCO3 during long-term storage under atm. conditions at room temperature proceeded on the buried copper surface to a depth of tens of nanometers. The phenolic resin nanofilm suppressed the thermal oxidation of the underlying Cu to Cu2O and CuO by 20% but did not suppress the formation of native oxides Cu(OH)2 and CuCO3 under atm. conditions because of the high water absorption and high permeability of the phenolic resin nanofilm. This study demonstrated that CEY-XAFS and HAXPES technique are the powerful tools for investigation of oxidation states of the copper surface buried under the phenolic resin insulating layer. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Safety of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.Safety of Cuprichydroxide
