Moiré Pattern of Bilayered Fatty Acid Monolayers Based on Dark Field Imaging

Moiré patterns of bilayered fatty acid monolayers prepared by the Langmuir-Blodgett method were successfully observed on the basis of dark field imaging by using transmission electron microscope for the first time. The moiré lines of the bilayered fatty acid monolayers prepared by the continuous compression method were warped and discontinuous, whereas that prepared by the multi-step creep method were straight and continuous. These differences apparently reflect their crystallographical regularities.
