Nanosecond relaxation processes and brownian motion of water-soluble polymers in micellar systems of surface-active compounds in organic solvents

Nanosecond dynamics of hydrated reversed surfactant micelles in organic solvents and its variation resulting from solubilization of water-soluble polymers and proteins in this micellar system were studied by polarized luminescence. The relaxation spectrum of such a system revealed the high-frequency and the low-frequency relaxation processes. The high-frequency motion in the hydrocarbon medium of the micellar system was associated with the mobility of individual surfactant molecules. The contribution due to that mobility increased with an increase in the degree of hydration of the micelles. When a polymer was incorporated into the micellar system, the transfer of macromolecules coupled to micellar fragments was observed in the hydrocarbon medium. This kind of motion was observed at low degrees of hydration of the micelles, and it became less significant as the content of water in the system increased.
