Complex Micellization Behavior of the Polysorbates Tween 20 and Tween 80.

Molecular Pharmaceutics, 2021
Polysorbates (PSs, Tweens) are widely used surfactant products consisting of a sorbitan ring connecting up to four ethylene oxide (EO) chains of variable lengths, one or more of which are esterified with fatty acids of variable lengths and saturation ...

Micellization Transformations of Sodium Oleate Induced by Gas Nucleation.

Langmuir, 2021
The interfacial properties of surfactant solutions are closely related to the micellization of surfactants. Temperature, salt type and concentration, pH, and other parameters affecting the micellization of surfactants have all been extensively ...

Micelles and microemulsions [PDF]

Annual Review of Physical Chemistry, 1992
We have shown that there is a close relationship between the surfactant film properties, the bulk structures, the interfacial tension with oil (or water) and even the dynamic properties in micellar and microemulsion systems. The evolution from spherical micelles to tubular, cubic, lamellar or sponge phases is now qualitatively well understood.

Wrapping Nanotubes with Micelles, Hemimicelles, and Cylindrical Micelles

Small, 2009
AbstractThis work uses a simple model based on hydrophobic and hydrophilic forces to investigate the molecular dynamics that lead to the supramolecular self‐assembly of surfactants around carbon nanotubes (CNTs). The effects of the concentration and the structure of surfactants are explored.

Spherulite‐Like Micelles

Angewandte Chemie International Edition, 2021
AbstractOne‐dimensional (1D) and 2D structures by crystallization‐driven self‐assembly of block copolymers (BCPs) can form fascinating hierarchical structures through secondary self‐assembly. But examples of 3D structures formed via hierarchical self‐assembly are rare.

Effect of changing alkyl chain in imidazolium based ionic liquid on the micellization behavior of anionic surfactant sodium hexadecyl sulfate in aqueous media

, 2020
The micellization behavior of anionic surfactant sodium hexadecyl sulfate (SHS) has been studied upon the addition of two imidazolium-based ionic liquids having different alkyl chains i.e., 1-propyl-3-methylimidazolium bromide [C3mim][Br] and 1-butyl-3 ...
