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 μm, a channel length of 500±2 μm, and a pattern depth of 7.34±0.5 μm. 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 Ω/sq, optical transparency values were 83.69% at a wavelength of 550 nm.
