Reappraisal of neutron scattering results on micellar solutions of dodecylhexaoxyethylene glycol monoether (C12E6)

Abstract

SANS data on micellar solutions of C12E6 as a function of temperature have been reanalysed using a cylinder growth model. Reasonably good fits to the experimental curves were obtained using only the rod length as an adjustable parameter. The effect of polydispersity in the micelle size on the scattering profile was also investigated. Our main conclusion is that SANS is not a sufficiently sensitive technique to allow a clear identification of the micelle structure(s) at elevated temperatures. © 1987 Steinkopff.
