Lyotropic liquid crystalline properties of nonionic surfactant/H2O/hexachloroplatinic acid ternary mixtures used for the production of nanostructuredplatinum

The effect of hexachloroplatinic acid (HCPA) on the liquid crystalline phas e boundaries of ternary systems containing a nonionic surfactant and water was investigated. The temperature and composition ranges of the liquid crys talline phases were affected dramatically by the presence of HCPA. In parti cular it was found that the presence of the platinum compound enhanced sign ificantly the stability of the more highly curved phases (I-1 micellar cubi c and H-I phases).
