Overview | Product Information | Related Products
Silver nanowires (AgNWs), like carbon nanotubes, are one dimensional (1D) nanomaterials with diameters in the order of tens of nanometres, lengths in the order of micrometres 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.
Similar product contains PEDOT:PSS is also available at Ossila, AgNW/PEDOT:PSS for highly conductive flexible electronics.
