The Change in Micellar Shape

To discuss further the shape and internal structure of the micelles, the hydrodynamic radii calculated from the self-diffusion coefficients according to Equation 10.2 were combined and compared with the SAXS results. The self-diffusion coefficient of a hard sphere at infinite dilution. Do, is described by [46], 

is the hard-sphere volume fraction. We use (p (volume fraction of copolymer) instead of for the calculation of Do because the exact volume of micelles is unknown. The concentration of Sii4C3EO is = 2 vol% so that the calculated values. Do, differs from D by -5% and this difference is noted as an error bar. 

According to LOW theory [16], the free energy of a single miceUe F is described as follows,
