Transparent “all-polymer” electrodes are promising candidates for applications in LCDs and LEDs and LEDs. A novel approach for making a new polyaniline-based polymer is described, efficient solubilization of the conductive from of polyaniline is reported, and use of the resulting conductive polymer solutions for LCDs demonstrated. The Figure shows a bent polymer-dispersed LCD with transparent “all-polymer” electrodes in the “on” (transparent) state.
