Inkjet printing technology is a widely used approach for producing flexible organic electronic devices and has such advantages as high speed of spot and contactless printing of functional layers of arbitrary shape and size. Organic Electrochemical Transistor (OECT) is one of rather simple devices for chemo- and biosensing, which allows achieving ultrahigh sensitivity. PEDOT:PSS, being an aqueous suspension of a complex of poly(3,4-ethylenedioxythiophene) with polystyrene sulfonic acid, is often used as a functional layer in OECT. However, such devices often required rather high gate voltage leading to their limited stability. One of the factors influencing their electrical characteristics is uniformity and good adhesion of the printed functional layer. To improve it, surface of the substrate before printing can be modified by UV/ozone curing, plasma treatment or chemically.
