Fabrication and Properties of Flexible OLEDs on Polyimide-Graphene Composite Film Substrate
In this work a clear polyimide (PI) film was synthesized by using selected monomers containing multiple CF3 groups. The polyimide-graphene composite films were made by film coating of mixture of polyamic acid (precursor of polyimide) solution with reduced grapheme oxide. The flexible OLEDs were fabricated by using the polyimide-graphene composite films on which the ITO/Ag/ITO thin films were deposited by roll-to-roll sputter instead of usual ITO-glass and the properties of flexible OLEDs were examined from the viewpoint of flexible substrates.
