Micellar Structure of an Ethylene Oxide−Propylene Oxide Block Copolymer: A Small-Angle Neutron Scattering Study
TL;DR: In this paper, small-angle neutron scattering (SANS) was used to examine micellar solutions of a highly hydrophilic ethylene oxide−propylene oxide triblock copolymer, pluronic F88, in aqueous solution.

Sodium chloride and ethanol induced sphere to rod transition of triblock copolymer micelles.
TL;DR: Dynamic light scattering, small-angle neutron scattering, and viscosity studies show that while the pure triblock copolymer solutions do not show any significant growth of the micelles on approaching the cloud point, the presence of a small amount of ethanol induces a sphere to rod shape transition of micells at high temperatures.

pH controlled size/shape in CTAB micelles with solubilized polar additives: A viscometry, scattering and spectral evaluation
TL;DR: In this paper, pH induced micellar transition in aqueous solution of cetyltrimethylammonium bromide (CTAB) in the presence of three weakly polar aromatic additives viz. p-toluic acid, p-cresol and p -toluidine was reported.

TL;DR: The composition of the copolymers plays a significant role in determining the influence of SDS on the gelation characteristics of the aqueous copolymer solutions, andCopolymers with high PO/EO ratios show an enhancement in the stability of the gel phase, whereas copolyers with low PO/OE ratios show a deterioration of the same in the presence of S DS.
