| 제목 | Dip-Pen Nanolithography of Conducting Polymer via Oxidative Polymerization |
| 초록 | Dip-pen nanolithography (DPN) technique allows one to directly pattern organic and inorganic molecules on a variety of surfaces with a coated atomic force microscope (AFM) tip in a controlled fashion on the sub-100 nm to many micrometer length scale.1 Covalent bonding on the usual "thiol ink/gold paper"combination is typically used as a driving force for moving the molecules from the tip to the substrate. Herein, we use "oxidant ink/monomer-coated semiconductor paper" combination for the deposition of polyaniline (PANI) conducting polymer on SiO2 surfaces using DPN. An ammonium persulfate (as the oxidant)-coated tip is brought into contact with the aniline monomer modified substrate surface. The oxidant molecule, transported from the tip to the surface through the water meniscus, can polymerizes the aniline monomer on the substrate by the oxidative polymerization2 resulting in the successful deposition of PANI conducting polymer on the semiconductor surface. Characterization of the patterned PANI nanostructures was performed by AFM. Significantly, we show that the oxidative polymerization can also be used as a driving force to pattern high-molecular weight molecules for the DPN process. 1. R. D. Piner, J. Zhu, F. Xu, S. Hong, C.
