Scientists achieve nano silver breakthrough to revolutionize the Printed Electronics industry
Electronics Using Flexible Substrates Can Be Cost-effectively Produced Using New Nano Formulations
Printed Electronics is considered by many to be the next revolution in the field of commercially viable Electronics. Goldsol Inc., through a cooperative relationship with materials science researchers at Clarkson University, has released a revolutionary new nano silver formulation that features a high concentration (up to 60% silver content), sub-20nm silver colloidal solution and can be specifically formulated for conductive ink or thin film applications. Goldsol’s AGX formula is unique in that its nano particles are not coated by other substances, yet the particles remain suspended, even at 60% concentrations. The use of coating agents often cause complications, such as reduced conductivity and potential degradation of performance over time as the coating agents may break down.
Goldol’s AGX formula also features very low sintering temperature characteristics, making it perfectly suited for printed electronics. electronic tracers need to sinter (melt) at a temperature that is low enough that the substrate on which they have been printed does not itself melt in the process of curing the printed metal traces.
The Holy Grail of the mass production of versatile electronics using flexible substrates consists of the confluence of technologies that include: the development of suitable plastic and other substrate materials themselves, the development of machines to manufacture the substrates and to print conductive traces on them, and the development of suitable conductive inks that can be effectively applied on the substrates as printed conductive patterns. Goldsol has successfully taken a dramatic technological leap in the last of these requirements by formulating a revolutionary nano silver solution for printable conductive ink applications. Other researches from many established and start-up companies are also making substantial headway in refining both the flexible substrate technologies and the building of a new generation of machinery built specifically for printed electronics manufacturing applications. The convergence of the necessary foundational elements for viable mass-produced flexible electronics is upon us!
Silver has been extensively used in the manufacture of electronic components for decades, as have its metal cousins, copper and gold. Nano researchers have held forth the promise that they can reduce the amount of expensive metal content required for various electronic applications through the deployment of small particle size clusters (<100nm) in contrast with the larger size particles (>100nm) of traditional approaches. The less metal needed, especially when one is using expensive metals like copper, silver, and gold, translates into lower cost. The nagging problem has been that the added cost of making the nano solutions themselves has more than offset the savings in metal content that the solutions offered, rendering them unviable as alternatives to traditional methodologies. That is, until now.
Professor Dan Goia Ph.D. and his team at Clarkson University are the geniuses behind the development of this solution. Professor Goia is widely considered one of the world’s foremost experts in precious metal materials science. He has developed dozens of precious metal solutions for commercial applications, and regarding this breakthrough, he recently stated, “This is the most exciting discovery we have made to date with regard to Silver Nanoparticles. Our novel formula has unique properties that make it ideal for conductive ink and thin film applications. We believe that our process may finally provide a functional and cost-effective solution for printed electronics.” He went on to say that this process is easily scalable to volume commercial production, which has also been a major stumbling block for other nano-particle based inks.
Goldsol Inc. has entered into an exclusive license agreement with Clarkson University to manufacture and distribute the product. Steve Crimi, Goldsol’s CEO said, “Our mission is to develop the most advanced metal nano-materials available. In the case of printed electronics, it’s not just about making a better conductive Ink. There is no doubt that our new silver is a major breakthrough. However, other materials and manufacturing processes have to be developed and commercialized before we can reach mass adoption.”
Goldsol is taking a cooperative approach to solve this problem by forming strategic alliances with industry partners in an effort to develop complete solutions for the electronics industry.
The Printed Electronics market segment is expected to grow at a CAGR of 33% and to reach $40 Billion by 2020. It is widely anticipated that, by 2020, solar cells, OLED’s, RFID tags, sensors, wearable electronics, and many other electronic circuits will be printed on plastic film, similar to the way we print ink on paper today.
