Realization of adhesion enhancement of CuO nanowires growth on copper substrate by laser texturing

Multi-layered micro-patterns co-printed with Ag@CuO nano-ink for flexible devices

“…To avoid oxidation and enhance stability, copper oxide ink is made from copper dissolved in a specific solvent, which is suitable for preparation and printing, and then copper oxide is reduced to copper after laser sintering, forming the micro-pattern. Yan et al [20] printed micro-patterns with copper oxide nano-ink prepared by thermal oxidation, and the results showed that the micro-pattern sintered by laser has a relatively low resistance and high adhesion, making it attractive for various applications, including functional layers and devices. Jones et al [21] proposed a direct laser write (DLM) process to fabricate micro-patterns by rapidly depositing CuO onto the substrate.…”

Cu3N/Cu2O core–shell nanowires: growth and properties

“…Nevertheless, it has been shown that the integrity of the CuO NWs can be improved by texturing the surface of the Cu foil. 26 It is interesting to point out here that CuO NWs have been used in dye sensitized solar cells, 27 sensors, [28][29][30][31] as well as for catalysis 32 so the growth, properties and applications of CuO NWs is an ongoing topic of active investigation which is interesting from a fundamental and technological point of view. 33 To the best of our knowledge, no one has investigated previously the conversion of CuO into Cu 3 N NWs under NH 3 : H 2 which is similar to our earlier investigations on the conversion of Ga 2 O 3 into GaN NWs under NH 3 at elevated temperatures.…”

Copper oxide@cobalt oxide core–shell nanostructure, as an efficient binder-free anode for lithium-ion batteries

“…However, this approach has one main challenge, restricting its practical applications. The low adhesion between the formed copper oxide NWs and the remaining copper substrate can result in cracking of the NWs layer and its exfoliation from the substrate, causing a significant problem during the operation of related functional devices [36][37][38]. To benefit from the advantages of the thermal oxidation method and preventing the problem of low adhesion of copper oxide NWs to the copper substrate, multiple solutions have been proposed.…”
