文摘

Dependences of the composition and properties of the monolayers and Langmuir–Blodgett films of yttrium, barium, and copper stearates on the conditions of their formation were studied by FTIR spectroscopy, X-ray photoelectron spectroscopy, and quartz crystal microbalance technique. The identity of film compositions on the surfaces of liquid and solid substrates was established. It was shown that, in the case of copper and yttrium, the Langmuir–Blodgett films are formed from corresponding basic salts of stearic acid at high subphase pH values. The conditions of the preparation of high-quality Langmuir–Blodgett films from yttrium, barium, and copper stearates are determined.
