Title: Effects of surface tension and viscosity on gold and silver sputtered onto liquid substrates

Abstract

Here, we report on DC magnetron sputtering of gold and silver onto liquid substrates of varying viscosities and surface tensions. We were able to separate the effects of viscosity from surface tension by depositing the metals onto silicone oils with a range of viscosities. The effects of surface tension were studied by depositing the metals onto squalene, poly(ethylene glycol), and glycerol. It was discovered that dispersed nanoparticles were formed on liquids with low surface tension and low viscosity whereas dense films were formed on liquids with low surface tension and high viscosity. Nanoparticles were formed on both the liquid surface and within the bulk liquid for high surface tension liquids. Our findings can be used to tailor the metal and liquid interaction to fabricate particles and films for various applications in optics, electronics, and catalysis.
