摘要: Nonionic surfactants containing poly(ethylene oxide) are chemically simple and biocompatible form core–shell micelles at a wide range of conditions. For those reasons, they their aggregates have been widely investigated. Recently, irregularities that were observed in the low-temperature behavior kind [CH3(CH2)nO(CH2CH2O)mH], (abbreviated CnEm) assigned to freezing–melting phase transition micellar core. In this work we expand focus from case single component systems binary surfactant temperatures between 1 15 °C. By applying small-angle X-ray scattering (SAXS), differential scanning calorimetry (DSC), nuclear magnetic resonance (NMR), density measurements pure C18E20 C18E100 solutions mixtures, show core freezing/melting is also present mixtures. Additionally, comparing SAXS data obtained mixture with components, it was possible demonstrate le...
