LB膜の表面構造の評価

抄録

Replicas for TEM observation are made with the films plasma-polymerized by a recently developed discharge glow method. The replicas allow visualization of the surface pressure-area curve, demonstrating numerous images of a monomolecular layer transferred from an aqueous subphase onto a glass plate at various surface pressures. The TEM technique is expected to assist preparation of the so-called Langmuir-Blodgett (LB) film without any extra structural defects on the electron microscopic scale. The method enables us to obtain some informations on normalizing the film properties for the practical use of them. We exemplify the normalization for a NO₂-responsible monolayer of amphiphilic phthalocyanine with a smooth surface produced by a subphase-lowering technique developed previously.
