title: Helical carbon and graphitic films prepared from iodine-doped helical polyacetylene film using morphology-retaining carbonization.
abstract: In this communication, we report a novel preparation of the helical carbon nanofibril-fabricated thin film from the iodine-doped filmy helical polyacetylene through a carbonization process. Carbonization of the helical polyacetylene films by way of iodine doping is found to afford carbon and graphitic films completely preserving morphologies and even helical nanofibril structures.
