Nature of CTAB/Water/Chloroform Reverse Micelles at Above- and Subzero Temperatures Studied by NMR and Molecular Dynamics Simulations
Original language description
The nature and stability of cetyltrimethylammonium bromide (CTAB) reverse micelles in chloroform formed above the critical micellar concentration at above- and subzero temperatures were examined by NMR and molecular dynamics simulations. The experimentsshowed that the supercooled micellar water pool becomes unstable upon cooling to relatively high temperatures (253 K), and smaller micelles are formed. Upon freezing at lower temperatures (233 K), micelles become completely frozen and remain intact in the solution. With an average hydrodynamic radius of approximately 1.3 nm, we estimate that the water pool contains approximately 50 water molecules, which is well below the onset of ice crystal formation. To support the experimental results, molecular dynamics simulations were used to model the structure of CTAB/water/chloroform reverse micelles of different sizes.
