Pass Through

During the initial stages of the oxidation of a clean metallic copper surface, and before the normal black colour of cupric oxide is finally attained, bright colours appear which pass through the first and second orders of the series of colours observed and tabulated by Newton as characteristic of thin films of air of increasing thickness. These facts have been known for a considerable time, but though the interference colours of thin films of air and those of the oxide film are produced in the same order, grave doubts have existed as to whether interference was the cause of the colours shown by the copper. This problem has been approached from measurements of the intensity of the light reflected from copper oxide films of known thickness, and the results show that interference is actually the cause of the production of the colour, though the result is complicated by the opacity of the film, the dispersion of the oxide, and the scattering of the light complementary to the film colour when the metal is burnished.

Assembly Procedure

Self-assembly procedure is employed to synthesize colloidal copper nanoparticles (ccNPs) with cationic surfactant in an environmentally friendly method. Scanning electron microscopy images provide a clear view of the ccNPs formed having an approximate size of 15 nm. The X-ray diffraction reveals that the ccNPs have the two types of copper oxide as well as the metallic copper. The new procedure shows that the cationic surfactant CTAB plays an important role in the understanding and development of self-assembly. There is a strong relationship between the ccNPs formation with the critical micelle concentration of the CTAB which influences both shape and size. The outcomes allowed the development of a molecular model for the ccNPs synthesis showing that the CTAB monomer on the surface has the function of a molecular velcro making the linkage of ccNPs to form an agglomerate with size around 600 nm. Finally, with the emerging new technologies, the synthesis of copper oxide takes a new perspective for their applicability in diverse integrated areas such as the flexible electronics and energy.
