Preparation of a brush-painted stretchable electrode. (a) Ag nanowire and conducting PEDOT:PSS mixed ink (20 ml:1 ml). (b) Optical micrographs of a brush before and after dipping in the mixed Ag NW/PEDOT:PSS (AP) ink. (c) Schematic illustration of the brush painting process. Pictures show the writable and paintable electrode made by simple brush painting using different types of paintbrushes. (d) Brush painting process using mixed ink for laterally aligned Ag NWs in a PEDOT:PSS matrix. (e) Cross-sectional TEM image of a brush-painted stretchable hybrid electrode on PU substrate. The arrow indicates the electrode region on PU substrate. Brush process in (c) and (d) was drawn by using a RHINO drawing program.
