The UV-Vis sintering process was applied for the fabrication of conductive coatings composed of low-cost nickel-silver (Ni@Ag) nanoparticles (NPs) with core-shell structures. The metallic films were formed on a plastic substrate (polyethylene napthalate, PEN), which required their sintering at low temperatures to prevent the heat-sensitive polymer from destroying them. The UV-Vis sintering method, as a non-invasive method, allowed us to obtain metallic coatings with good conductivity at room temperature. In optimal sintering conditions, i.e., irradiation with a wavelength of 350-400 nm and time of 90 min, conductivity corresponding to about 30% of that of bulk nickel was obtained for the coatings based on Ni@Ag NPs.
紫外-可见烧结工艺被用于制备由具有核壳结构的低成本镍银（Ni@Ag）纳米颗粒（NPs）组成的导电涂层。金属膜形成在塑料基板（聚萘二甲酸乙二醇酯，PEN）上，这需要在低温下对其进行烧结，以防止热敏聚合物被破坏。紫外-可见烧结方法作为一种非侵入性方法，使我们能够在室温下获得具有良好导电性的金属涂层。在最佳烧结条件下，即波长为350 - 400 nm的照射和90分钟的时间，基于Ni@Ag NPs的涂层获得了约为块状镍电导率30%的电导率。
