摘要：

The formation of colloidal and liquid crystalline aggregates of aluminium dodecylbenzene-sulphonate caused by mixing aqueous solutions of Al(NO3)(3) and dodecylbenzenesulphonic acid (HDBS) was investigated by light scattering and polarizing microscopy. Applying a fractal approach, some aggregates can be considered as multifractals and some as fractals, depending on the slopes of the 'lgI(Q) versus lg Q' plots (for multifractals the slopes are > 3). A model of multiscaling for the calculation of fractal dimensions in the formation of the liquid crystalline phases is proposed, describing both the spacial and the temporal dependence of amphiphile self-aggregation. The basic symmetries of the dynamics of formation and the structures of the liquid crystalline phases were found to be consistent.
