Abstract

The AgNWs PEDOT:PSS/PET transparent conductive films with high bendability and low optical haze were prepared by a facile spraying process combin in g with mechanical press treatment . When the ratio of PEDOT:PSS solution vs. AgNWs is 0.2, t he conductive film has excellent properties with a sheet resistance of 80.3 Ω/sq , transmittance of 87.4 %, a haze of 5.5% and a surface roughness of 25.6 nm. After being mechanically pressed under 4 M P a pressure, the film possesses a sheet resistance of 39. 5 Ω/ sq, transmittance of 87.4 % and haze of 4.3%. The adhesion and bendability a re also greatly enhanced with only 15.6% increase of sheet resistance after 20,000 bending cycles..
