|Title:||Purification Chemical Structure Electrical Property Relationship in Gold Nanoparticle Liquids|
|Published:||August 01, 2010|
|Abstract:||Macroscopic assemblies of nanoparticles are a new class of materials that exhibit unique properties compared to both bulk and isolated nanoparticle states. To more accurately probe the structure-property relationships of these materials, this report proposes a synthetic scheme which affords a high degree of control over the purity of each intermediate product. Rigorous purification and characterization at each step are key elements of this scheme, thereby increasing final product reproducibility for a wide range of amine-containing surface molecules. A range of tertiary and quaternary amines were used to successfully synthesize nanoparticle liquids from a range of gold nanoparticle starting materials, sized from 6 nm to 20 nm and initially coated with either citrate or dodecanethiol. The application of improved device performance in a RF-MEMS relay-switch was demonstrated by lifetime improvement of at least two orders of magnitude greater number of cycles before device failure.|
