Preparation of transparent and conductive silver nanowires films by screen printing method

Silver nanowires with high purity are focused as conductive media to prepare silver nanowires films (AgNWs-Films) on the glass substrate by using low-cost screen printing. After annealed at low temperature, the morphologies of AgNWs-Films films are characterized by field emission scanning electron microscopy. The optic transmittance and conductivity properties of the films are measured by ultraviolet-visible spectrophotometer and four-point probe, respectively. The influences of mass percentages of silver nanowires, the layers of AgNWs-Films and the annealing temperature on the optical and electrical properties are serially studied. It is concluded that within the mass percentages of AgNWs at 3%(Ww) and layers up to 3, the surface square resistence of AgNWs- Films can be as low as 25.6 Ω • ࢮ^-1, and the transmittance of films can be 39.4% after annealed at 275 °C.
