Highly homogeneous silver nanowire films with few silver nanoparticles are prepared with the method of improved vacuum filtration. Silver nanowires are pressed on the flexible substrates in order after processing vacuum filtration on the same substracte and repeat it for several times. The surface topography and the distributions of transmittance and sheet resistance of manufactured transparent conductive films are discussed. The result shows that the average sheet resistance of the film fabricated by three-times vacuum filtration reaches 7.47 Ω/sq with a transmittance of 82.5%.
