Abstract

The use of modifiers such as disulfides and phosphines is particularly effective in modifying the properties of metals such as noble metals and silver. For example, disulfides are useful for modifying the properties of gold and silver while phosphines are useful for metals such as platinum and palladium. Through treatment with a suitable modifier it is possible to change properties such as the wetting and adhesion properties of the treated metal. Additionally, the use of modifiers to treat a desired substrate enhances formation of continuous metal films on this substrate.
