A NANOLITHOGRAPHY technique for patterning conducting polymer nanostructures on semiconducting & insulating surfaces could help facilitate the fabrication of polymer nanodevices for use in the electronics, defense, pharma., & biotech. Industries The team used a direct-writing technique known as ELECTROCHEMICAL DIP-PEN nanolithography to prepare well-defined POLYTHIOPHENE lines with widths of < 100 nm on oxidized Si wafer surfaces The polymer lines are prepd by coating a atomic force microscope tip with 3,4-EthyleneDiOxyThiophene (EDOT) & then translating the tip across the Si wafer. The monomer is electrochemically polymerized at the interface by applying a voltage between the tip & the wafer. The morphology of the nanowires is controlled by varying the humidity, applied voltage & tip translation speed Poly-EDOT is a well known conducting polymer that has already attracted commercial interest for use as antistatic, electrostatic & conducting coatings as well as for light-emitting diodes |
