摘要
A cubic phase (I1) forming between the isotropic micellar and the hexagonal H(alpha) phases was detected in the hexadecylpyridinium chloride/formamide and hexadecyltrimethylammonium chloride/formamide systems. The lattice parameters of the phase were determined by X-ray diffraction. Attribution of the space group Pm3n and the size of the ordered micelles was based on the models proposed by Fontell, Charvolin, and Vargas. The structure of this phase was supported by transmission electron microscopic examination of the freeze-fracture replica.
