Conducting polymers have recently received much attention in light-emitting diodes (OLEDs), organic field effect transistors (OFETs), electrochromic devices and sensors because of their unique properties such as metal–insulator transition induced by doping–dedoping processes, optoelectronic properties controllable through molecular design. In comparison to other conducting polymers, Polyaniline (PANI) is one of the most widely studied conducting polymers due to the reversible and relatively simple doping-dedoping pathway, high conductivity and excellent environmental stability. In this work, we have fabricated the PANI patterns with feature sizes ranging from micrometer to nanometer. The self-assembly of block copolymers and colloidal particles was used as a template to produce platinum pattern required for electroless polymerization of PANI. It was observed that the PANI pattern was formed along the platinum that acted as a catalyst for spontaneous electrochemical reaction. |
