Metallic coloration and multiple functions were prepared on polyester woven fabrics via nitriding reactive magnetron sputtering with copper and titanium targets. The resulting colors ranged from light gray to pale yellow. The color of the copper film-coated fabrics was affected by elemental Cu, Cu2O, and Cu(OH)2 in the films. These species had a bandgap of 2.16 eV and a corresponding absorption edge of 574 nm. The color of the titanium film-coated fabrics was tuned via TiO2 and TiON with a bandgap of 2.35 eV and a corresponding absorption edge of 528 nm. The films’ color brightness and the optical bandgap decreased with a red shift in the absorption edge for the absorption of visible light. This phenomenon increased as the film thickness increased with increasing sputtering current. The UV protection performance of the copper film-coated fabrics was significantly and rapidly improved by increasing the sputtering current. An average UPF of 234.1 and an average improvement of 287.3% were obtained for the CuN series samples. The elimination of static electricity was improved for the two series of coated fabrics. This research offers a reference for structural coloration or metallic coloration on textiles and the preparation of functional textiles. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application In Synthesis of Cuprichydroxide).
Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.Application In Synthesis of Cuprichydroxide
