Supramolecularly Engineered Amphiphilic Macromolecules: Molecular Interaction Overrules Packing Parameters.
TL;DR: For either series of polymers, variation in the hydrophobic/hydrophilic balance does not alter the morphology reconfirming that self-assembly is primarily driven by directional molecular interaction which is capable of overruling the existing norms in packing parameter-dependent morphology control in an immiscibility-driven block copolymer assembly.
Viscoelastic fluids originated from enhanced solubility of sodium laurate in cetyl trimethyl ammonium bromide micelles through cooperative self-assembly.
TL;DR: The dynamic rheological responses of long micelles are consistent with a Maxwell type viscoelastic behavior, and the variation in the optimum interfacial area occupied by the surfactant as a function of electrolyte concentration is consistent with the model predicted by Nagarajan.
Effect of a Hydrophilic PEO–PPO–PEO Copolymer on Cetyltrimethyl Ammonium Tosylate Solutions in Water
TL;DR: In this article, small angle neutron scattering (SANS) measurements were used to quantify the interaction between CTAT and TBC-F87 and showed that penetration of PPO inside CTAT micelles decreases hydrophobicity of the core while the presence of PEO end blocks enhances hydrophilicity each favoring smaller micells.
Effect of amphiphilic and non-amphiphilic polymers on micellar behaviour of nonionic surfactant Triton X-100
TL;DR: In this article, Triton X-100 (TX-100) with nonionic polymers, namely, polypropylene glycol (PPG), polyethylene glycols (PEGs), as well as triblock copolymers PEG-PPG-PEG and PPGs, were studied.
