Abstract

Abstract Infrared reflection-absorption spectra of LB films of Cd, Ca, Ba, and Al stearates were measured at elevated temperatures, and thermal stability of the films was semiquantitatively examined. The conformational disorder suddenly increased at 110 °C for Cd salt, at 125 °C for Ca salt, and above 150 °C for Ba and Al salts. The spectral changes for the LB films subjected to cyclic thermal treatments were also studied.
