Sažetak
The morphology of freshly prepared as well as of aged cadmium dodecylbenzenesulphonate precipitates showed significant differences between the crystalline and liquid crystalline samples, as shown by transmission-, and scanning electron microscopy at room temperature. Since water evaporated from the samples during the investigation, the remaining material from the liquid crystalline phase gave data on the shape and size of the aggregates. It was shown that electron microscopy at room temperature gives useful information on the lyotropic liquid crystalline phases, presuming the physical parameters were compared with some other techniques, such as X-ray diffraction and light microscopy using crossed polarizers.
