Copper oxide (CuO) is a low-cost and stable semiconductor and has promising applications in wearable devices or smart textiles. However, divalent nature of copper atoms makes it difficult to assemble on most synthetic fibers and usually display a poor distribution on fiber surface. This was addressed through using manganese as a transition metal to create complex with copper ions. Subsequently, a core/shell structure was obtained since copper ions had lower reduction potential than manganese ions. Thus, the preformed CuO nanoflowers (core) were uniformly covered by many small coarse MnO2 particles (shell). The created core/shell structure endows synergistic mechanical, self-cleaning and antibacterial properties on the fabric and more importantly, significantly improved the affinity and the distribution of CuO nanoflowers on the nylon fabric. The synthesized particles and treated fabrics were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, dispersive X-ray spectroscopy (EDX), X-ray Diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR).Graphical Abstract
