Well-Aligned Ultra-High Density Array of Conducting Polymer Nanowires using Block Copolymer Nanoporous Templates |
초록 |
Conducting polymer nanowires with high density have attracted much attention, due to their various applications including electrochromic devices, organic photovoltaic devices, polymer nano actuator and drug delivery. Here, we proposed a new template-based synthesis method using polystyrene-block-poly(methyl methacrylate) copolymers (PS-b-PMMA) nanoporous template to fabricate conducting polymer nanowires. Well-aligned ultra high density arrays of polypyrrole (Ppy) or poly(3,4-ethlenedioxythiophene) (PEDOT) nanowires were prepared on the ITO glasses by electropolymerization inside holes of the nanoporous templates. These nanowires grown inside nanoporous templates have much higher conductivity compare to films. We find out that high conductivity results from the well-aligned chain orientation of nanowires because they were grown inside confined holes. So, ‘confinement effect’ is very important for higher conductivity and well-aligned structure of conducting polymer nanowires. |
