Observation of individual fluorine-atoms from highly oriented poly(tetrafluoroethylene) films by atomic force microscopy

摘要

In recent years,there has been an increasing interest in properties of unidirectional materials grown on highly oriented polymer surfaces such as the poly(tetrafluoroethylene) (PTFE) films coated onto smooth glass surfaces.The technique for depositing a highly oriented,thin film of PTFE as a substrate for oriented growth of materials was first demonstrated by Wittmann and Smith.
