摘要

A copper nanoparticle-sulfuric disazo dye (Cu-SD1) composite was synthesized using the sol-gel method. Cu-SD1 nanocomposite formation was monitored by ultraviolet-visible spectroscopy (UV-vis). The acquired experimental results suggested that 8 h of reaction is needed for the synthesis Cu-0 nanoparticles. Transmission electron microcopy (TEM) and atomic force microscopy (AFM) were employed to elucidate the morphology of the Cu-SD1 nanocomposite. It was found that the diameter of particle sizes were in the range of 2-4 nm. The interaction of SD1 with copper was confirmed by Fourier transform infrared spectroscopy (FTIR). The peak shift of O-H and C-OH functional groups indicated the interaction between SD1 and copper nanoparticles. Moreover, the azo group (N=N) peaks were suppressed after the formation of the nanocomposite, suggesting that a strong linkage was formed between the functional groups and the copper nanoparticles. The surface composition and chemical states of the as-synthesized copper nanoparticles were elucidated by X-ray photoelectron spectroscopy (XPS). In addition, photo-switching of the composites was elucidated in the solution state. It was found that the Cu-SD1 nanocomposite has a faster switching response compared to the parent, SD1, in a solution.
