Highly Transparent Conductive Sheet by Self-assembled Silver Network Electrodes with Antireflective Coating via Roll-to-Roll Process
Faculty of Science and Technology, Keio University, 3-14-1 Hiyoshi, Kohoku-ku, Yokohama 223-8522, Japan
A highly transparent conductive film was fabricated using self-assembled silver electrodes with anti-reflection (AR) film. The micro pore diameter of sliver nanoparticles (ca 50～60nm in diameter) network electrodes expanded to size of 200-300 μm by the increase of air voids with evaporated water. The transmittance of the silver network electrode increased was drastically increased by the optical interference from the AR film on the surface and it showed a maximal value 84％ (sheet resistance: 8.0 Ω/□). The surface resistance of silver network electrodes films did not change even after coating with the AR films because thickness of AR films (ca 100～200 nm) are extremely thin compared with the diameter of the silver wire (ca 3 μm). High performance transparent conductive film for electric and optical devic was successfully fabricated by roll to roll layer-by-layer (LBL) process.
