Fig. 1: Process and patterned features of photopatternable PEDOT:PSS.

a Water contact angles depending on the film composition and UV exposure. After addition of P123 in the film composite, wetting occurs only after UV exposure. b Change of contact angles. c Photopatterning process of PEDOT:PSS. The UV-exposed area becomes soluble in water within 10 s. d Stereomicroscope images of patterned PEDOT:PSS films. The scale bar lengths from the left are 1000, 500, and 200 μm. e Images of PEDOT:PSS films on the SEBS substrate that show transparency and stretchability.
