US Patent 7763187 Carbon nanotubes-reinforced conductive silver ink

Conductive silver ink is reinforced using carbon nanotubes. Carbon nanomaterials are stabilized and uniformly dispersed in a solvent and mechanically mixed with conductive silver ink. The reinforcement material bridges the gap between separated silver flakes in the conductive silver ink. The carbon nanotubes reinforced conductive silver ink exhibits superior performance over unreinforced silver ink in its mechanical, electrical and thermal properties without significantly greater weight.
