Silver nanowires (AgNWs), like carbon nanotubes, are one dimensional (1D) nanomaterials with diameters in the order of tens of nanometers, lengths in the order of micrometers and high aspect ratios of over 100.
Silver nanowires are known to have high electrical and thermal conductivities, high surface area, excellent optical property, great flexibility, low light extinction in the visible, flexibility, and antibacterial characteristics. Silver nanowires have been incorporated into a wide range of products from photovoltaics to biological sensors. AgNWs dispersion can be processed by solution deposition to fabricate patterned stretchable conductors with feature size as small as 50 μm.
Silver nanowires are most commonly produced with narrow size distribution and high aspect ratio by polyol method using poly(vinylpyrrolidone) (PVP) in ethylene glycol (EG) to reduce Ag+ into silver nanoparticles. With a diameter of <30 nm and length of >20 μm, a high purity of >99%, silver nanowires water dispersion finds use in a range of applications.
From flexible electronics to sensors and catalysis, silver nanowires are versatile, and popular within a range of scientific fields. Flexible electrodes are particularly useful for lithium-ion battery chemistry where issues of volume change can introduce safety problems. Silver nanowire electrodes, with three-dimensional nanostructures, prevent issues associated with the volume contraction and expansion of lithium ion batteries during alloying processes.
