| We demonstrated a sub-micron size pattern of poly (ethylenedioxythiophene) (PEDOT) that is grafted on flexible polymer substrates. The grafting method utilize phenylene moiety in polymer substrates. With this simple one-step method, PEDOT polymer film can be grafted on various kinds of polymer substrates. An enormous increase in adhesion strength was consistently observed. PEDOT films are highly conformal to the surface of the substrate. Even after 3 hours of ultrasonication treatment, the PEDOT film was not delaminated from the polymer substrate. Mechanical, chemical, thermal, and photo – stability were checked and neither conductivity nor chemical degradation were observed. Conducting polymer pattern was easily obtained using soft lithography technique and uniformly well-defined high-density line-and-space pattern was successfully obtained with the minimum resolution of 160 nm at the large area of at least 2 × 3 mm. The obtained conducting polymer pattern grafted on flexible substrate can be a breakthrough for integrated circuitry in flexible electronics and the easy one-step process of grafting can offer a wide process window and versatility in application to various flexible products. |
