Abstract

The recent development of microemulsion systems which do not separate during cooling and in which neither dispersed nor matrix phases crystallize during the cooling process permits low-temperature studies of the microemulsion structure and the investigations of common liquids in unusual states. Benzene, carbon tetrachloride, and CS2 all can be supercooled without limit in microemulsion form, and their glass transition temperatures have been determined. Transmission electron microscopy of thin vitrified layers permits high-resolution observations of water-diluted samples of the same microemulsions. Gas-like, liquid-like and solid-like (hexagonal) organization of the microemulsion droplets are observed. Other experiments must decide which of these structures are imposed by the thin-film preparation technique and which are natural arrangements of warm bulk microemulsions.
