Fabrication of transparent conductive electrode film using thermal roll-imprinted Ag metal grid and coated conductive polymer.

ABSTRACT

In this study, to fabricate a low-resistance and high optical transparent conductive electrode (TCE) film, the following steps were performed the design and manufacture of an electroforming stamp mold, the fabrication of thermal-roll imprinted (TRI) poly-carbonate (PC) patterned films, the manufacture of high-conductivity and low-resistance Ag paste which was filled into patterned PC film using a doctor blade process and then coated with a thin film layer of conductive polymer by a spin coating process. As a result of these imprinting processes the PC films obtained a line width of 10 +/- 0.5 Mm, a channel length of 500 +/- 2 microm, and a pattern depth of 7.34 +/- 0.5 microm. After the Ag paste was used to fill part of the patterned film with conductive polymer coating, the following parameters were obtained a sheet resistance of 9.65 Omega/sq, optical transparency values were 83.69% at a wavelength of 550 nm.
