Conductive Ink Composition

摘要

A representative printable composition comprises a liquid or gel suspension of a plurality of conductive particles; a first solvent comprising a polyol or mixtures thereof, such as glycerin, and a second solvent comprising a carboxylic or dicarboxylic acid or mixtures thereof, such as glutaric acid. In various embodiments, the conductive particles are comprised of a metal, a semiconductor, an alloy of a metal and a semiconductor, or mixtures thereof, and may have sizes between about 5 nm to about 1.5 microns in any dimension. A representative conductive particle ink can be printed and annealed to produce a conductor.
