Resumo
Silver nanowires thin films have gained attention due to their excellent optical and electrical
properties, being a potential material to be applied in optoelectronic devices as transparent
conductive films, deposited on a substrate in a such way that forms a percolated network. We
report the synthesis of silver nanowires with average length of 9.5 ± 0.4 μm and diameter of
75 ± 3 nm by a modified polyol method and fabrication of transparent and conductive thin films
using a simple and low-cost technique as drop-casting. Additionally, we examined the influence
of the drop-casting method in function of number of deposition cycles on the optical and electrical
properties of the films through optical absorption and electrical resistance measurements using the
two-point methodology. Increasing the number of silver nanowire deposition layers, the optical
transmittance decreased from 97 (for one layer) to 60% (for five layers), and electrical resistance
decreased from 940 ± 0.35 Ω for the 2-layer film to 32 ± 0.02 Ω, for the 5-layer film. Due to the
electrical conductivity range of the produced silver nanowires films, we suggested their application
in low-voltage circuits.
