Fabrication of Flexible Transparent Conductive Films with Silver Nanowire by Vacuum Filtration and PET Mold Transfer

The flexible transparent conductive films (FTCFs) of silver nanowire-polyethylene terephthalate (AgNW-PET) were prepared by a facile method including vacuum filtration and mold transferring. The effect of silver nanowire weight density on the optical and electrical properties of films, as well as the electrical percolation was investigated. The obtained typical AgNW-PET film exhibited high figure of merit of 31.3 × 10−3 Ω−1 with low sheet resistance of 4.95 Ω sq−1 and high transparency at 550 nm of 83.0% (excluding PET substrate). The resulting FTCFs based on PET substrate with high transmittance and low sheet resistance have a great potential in the application of high-performance flexible electronics and photovoltaic devices.
