Silver Nanowires are nanomaterials with high electrical conductivity, resistance to oxidation, and great optical & antibacterial properties. Silver Nanowires also performs great in transparent conducting electrodes for touchscreens, solar cells, flexible displays, sensors, light-emitting diodes, etc. These nanowires can be included in many products like textiles, antibacterial bandages, and EMI shielding.
Additionally, silver nanowires have been great as conductive fillers for combined applications. Now, it is essential that the minimum amount of silver is used for establishing the electrical connection in the final matrix, also known as the percolation threshold. Due to its high aspect ratio, silver nanowires can easily reach percolation at concentrations of less than 1%.
With great electrical, optical, and thermal properties, silver nanowires have great possibilities for developing advanced technology applications. They are available in powder and dispersion form. The Silver Nanowire powder can be easily blended with polymers, like polyurethane and epoxy, for EMI shielding, thermal conductors, etc.
Application
of Silver Nanowires
Silver Nanowires have been widely used in biological and electronic
applications, in addition to water sterilization and transparent conducting
electrodes. It has also been a favorable alternative to indium tin oxide for
electronics applications. One more beneficial factor of nano-silver is that its
properties can be adjusted to fulfill the printing technique requirements such
as roll-to-roll, gravure, spray printing, slot-die, flexographic, and inkjet
printing. Let’s see some more of its applications.
●
Optical: It
includes solar cells, SRP sensors, surface-enhanced spectroscopy, optical
equipment, medical imaging, etc.
● Conductor:
This includes intensive LEDs, conductive inks, touch screen display, conformal
electronics, filler for conductive adhesives, conductive adhesives, EMI
shielding coatings, smart fabrics, RFID antenna & batteries, and super
capacitors.
●
Chemical
and Thermal Applications: It consists of batteries, sensors, catalysts, heat
dissipation, etc.
● Antimicrobial
Applications: This includes coatings for medical devices, bandages, and
membranes for sterilization and water disinfection.
Final
Consideration
The nano silver technology, as a whole, has been broadly used these
days, in coating the surface of electronics, carbon blocks, woods, metals,
papers, ceramics, glass, fiber, etc. The essence of the Nano Silver technology
has been the ability to produce particles as small as possible and then
distribute them evenly. Moreover, the surface area of any material increases a
million times when the nanoparticles are coated on their surface. The increased
surface provides a strong antibacterial effect with just a small amount of
silver.
Due to their great electrical, optical, and thermal properties, silver nanowires will be used in the development of advanced technological applications, very soon. As silver nanowires are available in powder and dispersion forms, its usability also increases. For instance, silver nanowire powder is mixed with epoxy or polyurethane or any polymer for thermal conductors, EMI shielding, and other uses.
