Effect of surface pressure on the Langmuir-Blodgett polymerization of 2-pentadecyl aniline
In recent years there has been a renewed interest in Langmuir-Blodgett (L-B) films due to the improved nonlinear optical and electronic characteristics shown by polymeric L-B films. This paper will discuss the polymerization of a functionalized polyaniline. We have shown previously that 2-pentadecyl aniline can be chemically polymerized on a L-B trough. It was also shown that the change in the mean molecular area of the molecules at the air/aqueous interface could be used as a method to observe the polymerization process as it happens in a manner analogous to classical dilatometry of bulk polymerizations. During the polymerization of 2-pentadecyl aniline the mean molecular area was observed to decrease from 40-50 angstrom2 to a constant value of approximately 20-30 angstrom2 (depending on the applied surface pressure) as the polymerization was finished. The following text will discuss the effect of the applied surface pressure on this L-B polymerization.
