영문 초록

The mean gyration radii, Rg of elongated micelles and solubilizate incorporated micelle of sodium dodecyl sulfate(SDS) were measured using angular dissymmetry of the dynamically scattered light. The solubilizates were : benzene, naphthalene and anthracene. The measurements were performed at low NaCl concentration(0.05M) and high NaCl concentration(0.30M) at temperatures, 25°C, 30°C and 40°C. The measured Rg values were also compared with the theoretically derived values on the curves of the angular dissymmetry, (d(θ)) versus the cos θ of the solubilized SDS micelle. The SDS micelles added by NaCl and solubilizate molecules such as aromatic compounds are shown to behave thin rod-like between 228A and 579A in length, and flexible bended rod-like between 621A and 1059A in length, as the temperature goes down form 40°C to 25°C. As a result, the non-rigid SDS micelles transform gradually from sphere via prolate ellipsoid to thin rod-like and flexible bended rod-like micelles as the electrolyte and solubilizate molesules are added and the temperature is lowered.
