Silver Nanorings & Nanowires (Ring diameter: 10-20 um)

Silver Nanorings can be used as a conductive filler to formulate conductive Inks for different applications.  This ink shows better conductivity in comparison with the inks that only use silver nanowires as conductive fillers. This improvement is directly correlated to the shape of NR which creates more contact points between the rings on the substrate. Considering that Silver Nanorings of 100 nm should not be compared with the finer diameter of silver nanowires (20 nm) since thinner wire yields better optical properties.

Other potential applications are:

• Optical Applications: Optical limiters, Medical imaging, Solar Cells, Surface plasmonic devices, Surface-enhanced spectroscope
• Conductive Applications: Printed Electronics, Conductive adhesives, EMI shielding films and paints, smart clothes
• Antimicrobial Applications: Food preservation, Bandages, coatings for medical devices, Antibacterial textiles & fabrics
• Chemical & Thermal: Catalysts, Chemical vapor sensors, Detectors

Silver Nanorings (AgNR) are similar to silver nanowires (AgNW) having potentially better opto-electrical properties when compared with the same wire diameter of AgNW. We have reported and introduced for the first time AgNR as a new generation of TCF into the market with thread thickness of AgNR at 120 nm. This improvement is directly correlated to the shape of NR which creates more contact points between the rings on the substrate. Considering that AgNR of 120 nm should not be compared with finer diameter of AgNW since thinner wire yields better optical properties and seeing that our introduction AgNR has created much interest in the market, we are  studying to develop AgNR with finer diameter to improve its optical properties to surpass the properties of AgNW with much finer thread thickness of AgNR.

Silver Nanorings like nanowires are implemented in our conductive inks and conductive films to create a variety of different products and applications.
