Formation of polyimide films by the Langmuir‐Blodgett (LB) method is described. The preparation and possible applications of the films are detailed. In a mixed LB film of two different polyimides, friction force microscopy reveals hexagonal islands (see Figure), which is the first observation of two‐dimensional phase separation in a polymer mixture.
