Title

Probing the Solution Structure of Monodisperse Cylindrical Micelles Prepared By Gradient Crystallisation-Driven Self-Assembly

Abstract

Micelles prepared by the crystallisation-driven self-assembly of a mixture of brush and linear PFS containing block copolymers (BCPs), display segmented coronas when analysed microscopically in the dried state. However, their structure in solution is as of yet undetermined. The principal aims of this experiment are: to determine the precise microstructure of cylindrical BCP micelles prepared by the co-assembly of linear and brush BCPs, to characterise the longitudinal structure of their coronas as a function of brush length and to elucidate the self-assembly mechanism that governs their formation. SANS represents the only technique available to conclusively achieve these aims. D22 is required for a wide Q range and high intensity.
