Abstract Polyelectrolytes introduced in the aqueous subphase are shown to have a profound impact on the kinetics of polymerization of N ‐octadecylaniline at the air/water interface. This can be attributed to changes effected in molecular organization and reorientation behavior in the Langmuir film. The polyelectrolyte templates lead to considerable modification of the morphology of the monomer and polymer Langmuir films. Polyelectrolyte complexation is found to be an elegant and efficient methodology to achieve enhanced alignment of the polyaniline chains in the transferred Langmuir–Blodgett (Langmuir–Schafer) film.
