Abstract

High-energy ion beam irradiation of cross-linking type polymers gives nanowires formed by cross-linking reactions along the ion track trajectories. A fairly simple technique has been developed to control the size and number density of nanowires based on polystyrene (PS) by selecting appropriate ion beam characteristics and molecular sizes of the target polymers. This technique has also been extended to the formation of nanowires based on polyaniline (PANi) and poly(3-hexylthiophene) (P3HT). Characteristic optical properties (absorption and photoluminescence) observed for the various sizes of nanowires based on P3HT on a quartz substrate are different than those from solid state P3HT, suggesting that the nanowires are not just the finely patterned analogs of the conjugated polymers.
