Paper Abstract

Brillouin spectroscopy has been used to characterize the elastic properties of Langmuir-Blodgett (LB) multilayer assemblies. First, some of the data obtained with cadmium arachidate layers are reviewed. These show highly anisotropic elastic constants reminiscent of smectic liquid-crystalline materials with a very small ratio of shear to compressional moduli. Then, recent results obtained with polymeric LB films are presented. For a polyglutamate system the complete set of elastic constants could be determined.
