Polymer-based OLED is recognized as an ideal source for area lighting application for the potential large area production and approaching the required efficiency and unit brightness, and color rendering effects. In order to achieve low cost and high efficiency, it is crucial to have an air stale cathode with efficient electron injection properties.

Carbon nanotube (CNT) has been demonstrated as a viable electron injection material for OLED application, with the need to increase solubility and dispersion to improve performance.

In Phase 1, NanoTex proposes to use purified single wall type of CNT, combined with surfactant conductive polymer, to develop a stable solvent processible cathode for OLED applications.
