X-Ray Diffraction from LB Films of Fatty-Acids

Abstract

Abstract: The multilayers LB films of stearic acid and arachidic acid and their mixtures with various composition were effectively prepared by Langmuir-Blodgett technique. X-ray diffractions in the range with low angle were employed to detect the periodic structure of the LBfilms. Thirteen and twelve Bragg peaks were observed for stearic acid and arachidic acid LB films, respectively, in the 2θ angle range of 0.8°～23°. The periods of LB films were calculated from of-value of diffractive peaks. The even-odd intensity osscillations are successfully explained in terms of the model calculation. The periods with changing molar fraction in the mixture of LBfilms were observed and analyzed.

Key words: Stearic acid, Arachidic acid, Langmuir-Blodgett film, X-ray diffraction
