摘要：
The surface structure of a three-layer Langmuir-Blodgett film of comblike rigid-chain polyimide prepolymer (polyamic acid alkylammonium salt) has been studied by atomic force microscopy (AFM). The AFM data reveal the presence of supramolecular formations consisting of two-dimensional domains in which aliphatic chains of the prepolymer macromolecules are oriented perpendicularly to the substrate. A mechanism responsible for the supramolecular structure formation in the film is proposed.
