Knowingly or unknowingly, flexible electronics has become a part of our daily life. Transparent conductive films (TCFs) are used in mobile phones, tablets, laptops and displays. Currently, Indium Tin Oxide or commonly known as ITO is the material of choice. But use of ITO has some major disadvantages and these are brittleness, higher conductivity at greater transparency, and supply of Indium. This is where non-ITO materials come into play.
Based in St. Paul, Minnesota (USA), Cima NaoTech’s uses its SANTETM nanoparticle technology, a silver nanoparticle conductive coating which self-assembles into a random mesh like network when coated onto a flexible substrate such as PET and PC. According to a recent press release, the company stated SANTETM nanoparticle technology enabled transparent conductors in a multitude markets from large format multi-touch displays to capacitive sensors, transparent and mouldable EMI shielding, transparent heaters, antennas, OLED lighting, electrochromic and other flexible applications. Cima NanoTech is working with Silicon Integrated Systems Corp. (SIS) of Taiwan and using its highly conductive SANTE FS200TM touch films to develop large format touch screens.
