Nano silver powders foster new flexible printed circuits

The average particle size of The technology works on paper and polymers, and costs less to process than semiconductor technology. This can help drive widespread commercialization of radio-frequency identification (RFID) for inventory control and can foster adoption of electronic paper for e-books, thin-film batteries, flexible displays, and organic light-emitting diodes.</p> <p>The silver powder also has applications in conductive surface-mount adhesives and inks for connecting lines for denser circuits on cards and boards in smaller, faster electronic devices. </p> <p>The powder's surface chemistry can be tailored to optimize specific properties. And conductive inks, pastes, and adhesives made with them will have better controlled rheology and viscosity to produce finer, sharper line definition and lower deposition weights for printed circuits. This gives designers more freedom to incorporate electronics into broader applications than previously possible.</p> Additionally, the properties of Nano Silver 7000-95 offer advantages in nonelectronic applications. Silver kills odor-causing bacteria and neutralizes ammonia. Nano Silver 7000-95 promotes these activities, making it suitable for such emerging applications as antimicrobial-coated textiles for performance apparel, infection-resistant medical devices, and glazes for sanitary ware that permanently inhibit odors and stains without chemical cleaners. <p><b>MAKE CONTACT<br /> Ferro Corp.,<br /> (216) 641-8580,<br /> </b><i><b><a href=ferro.com
