Rising Mineral Prices Drive Conductive Ink Changes
roboma | June 25th, 2011 | Comments OffWith the rising prices of gold and silver, there is increasing pressure to develop replacements for conductive inks based on metal powders and flakes. The arrival of silver nanomaterials is enabling the expansion of silver inks and powders utilizing hybrid materials. Analysis by NanoMarkets indicates that “nanosilver inks have the potential to take printed electronics from the age of the membrane switch to the age of the printed sensor and backplane.” The use of hybrid materials, that combine silver powder or flake with less expensive materials, is expected to grow by more than 50% between now and 2016 worldwide. However the issue with hybrids is typically that they aren’t as conductive as the pure silver inks for example. With enhancements in nanomaterials, there is an opportunity for suppliers to market hybrids like silver-coated copper or silver-coated nickel fillers that have near the same conductivity at a far lower cost.
