31‐2: Invited Paper: Silver Nanowire Transparent Conductive Films for Flexible/Foldable Devices

In this paper we will report a superior transparent conductive ITO‐alternative material, ClearOhm® ink, developed by Cambrios Advanced Materials Corporation. ClearOhm® ink consists of a formulated dispersion of silver nanowires, which can be wet coated or printed to form a transparent conductive film. The coated film can achieve a wide range of sheet resistance from 5 to 300 ohms/square. Coatings on flexible PET film have excellent optical properties: > 91% total transmission and < 0.4 % total haze at 40 ohms/square or higher. The coated film can bend through a 1 mm bending radius for more than 350,000 cycles and stretch up to 4% strain with less than 10% resistance change, thus enabling emerging flexible/foldable displays. ClearOhm® silver nanowire films have been engineered for robust reliability. In this paper, we discuss the environmental stability of ClearOhm® silver nanowire films in accelerated aging tests, including the elimination of silver nanowire photo‐oxidation when exposed to UV light such as sunlight.
