Silver Electrodeposition from Room Temperature Ionic Liquid Electrolytes
Abstract
Reversible deposition of silver thin films has numerous industrial applications including, auto-dimming mirrors for the automotive industry, electrochromic windows for the aviation industry, smart glass for the architectural industry and mirrors or thermal emitters for deployment on orbital platforms. Room temperature ionic liquids possess a number of unique properties that make them attractive for reversible silver systems, such as their relatively high conductivity, large electrochemical and liquid phase window, and their ability to solvate high concentrations of metal ions of interest, making them an attractive alternative to conventional electrolytes such as cyanide-based electrolytes, which in addition pose toxicity issues. Use of RTILs in these systems is anticipated to enable deposition or stripping of thin films with specific optical, emissive and electrical properties that may be tuned as needed for specific commercial applications. Furthermore, use of RTILs is anticipated to be beneficial in space applications compared to conventional electrolytes due to their low volatility, preventing evaporation if exposed to vacuum, and their excellent chemical and thermal stability, which may enhance tolerance to orbital radiation.
