| Research Abstract |
A novel contact-printing technique, in which surface energy of the polydimethylsiloxane (PDMS) stamp was tuned reversibly by light irradiation, was proposed. The photochromic dye, spiropyran, allows the control of wettability of the PDMS stamp. We confirmed that spin-coated conductive polymer, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT/PSS), was formed selectively on the stamp without patterned reliefs. The patterned PEDOT/PSS can be successfully transferred and used as the electrodes in printed electronics. We demonstrated that modified stamp was useful for the fabrication of organic devices.
