Effect of Ag coating on the oxidation resistance, sintering properties, and migration resistance of Cu particles

Parametric study on conductive patterns by low-temperature sintering of micron silver ink

“…In the heating stage, the sample was first heated from room temperature to 70 °C, for the removal of organics, before sintering. 28 Then, pressure was applied onto the pattern with a rapid heating rate to obtain a higher sintering driving force at low temperatures. In the holding stage, the grain growth will be accelerated by prolonging the holding time, with the help of diffusion bonding between silver particles.…”

A collaborative diffusion mechanism of multiple atoms during Cu–Ag bimetal surface reconstruction

“…30 Recently, the study of dynamic CO adsorbate-induced restructuring of the Pd/Au(111) shown surface concentration of Pd was actively increased by CO over a period of B1000 s at room temperature. 31 Bimetallic Cu-Ag nanocatalysts have attracted a great deal of attention in glucose and ascorbic acid detection, 32,33 hydrogenation, 34 CO 2 electroreduction, [35][36][37] electronic industry, 38 etc. Many experimental studies have been performed to explore the catalytic properties of bimetallic Cu-Ag nanoparticles, but the study of surface reconstruction of Cu-Ag remains to be scarce.…”

Synthesis of Imidazole-Compound-Coated Copper Nanoparticles with Promising Antioxidant and Sintering Properties

“…Inorganic coating treatments use inorganic elements, such as silver [19,20], phosphorus [21], and tin [13], to form a compact protective film on the Cu particles. For example, in a study by Dai et al, cupric formate was heated to 170 • C in an oleylamine solution and was decomposed to form Cu nanoparticles [22].…”

“…The as-prepared particles could be stored in the air for 2 weeks without being oxidized. In a study by Yang et al, Ag-coated Cu nanoparticles were obtained by adding Cu nanoparticles into a solution with silver nitrate, ammonia, and a complexing agent [19,20]. The obtained particles were almost free of oxidation after exposure to the air for 48 days.…”
