Spray Coated Light Emitting Electrochemical Cells on Standard Polyester Cotton Woven Textiles

Abstract

In this article, we report the fabrication of LECs on wearable textile substrates. The standard polyester cotton woven textile substrate is smoothed by screen-printing the polyurethane layer that is then UV cured. Solution processable spray coating method is utilised to deposit all functional layers including top and bottom electrodes. The spray coating is performed inside the nitrogen filled glove box to avoid exposure of the ambient air. The LECs are fabricated on ITO glass substrates with the same process parameters as a reference device. Finally, the devices were sealed using encapsulation polymer and tested in the ambient air conditions.
