Effective mass density of liquid composites: Experiment and theory.

We present an effective medium theory based on the Maxwell-Garnett [J. C. Maxwell Garnett, Philos. Trans. R. Soc. London, Ser. A 203, 385 (1904); ibid. 205, 237 (1906)] and Bruggeman [D. A. G. Bruggeman, Ann. Phys. (Leipzig) 24, 636 (1935)] approximations, to investigate the effective mass density of binary and ternary liquid composites. Excellent agreement between our experiment and theory is shown. The results are well interpreted in terms of intermolecular interactions, which affect the miscibility between liquid components. Thus, it becomes possible to theoretically predict the effective mass density of liquid composites. [ABSTRACT FROM AUTHOR]
