Network Formation of Catanionic Vesicles and Oppositely Charged Polyelectrolyte...
Antunes, Filipe E.; Marques, Eduardo F.; Gomes, Ricardo; Thuresson, Krister; Lindman, Björn; Miguel, Maria G.In nonequimolar solutions of a cationic and an anionic surfactant, vesicles bearing a net charge can be spontaneously formed and apparently exist as thermodynamically stable aggregates. These vesicles can associate strongly with polymers in solution by means of hydrophobic and/or electrostatic interactions. In the current work, we have investigated the rheological and microstructural properties of mixtures of c...
A rheological investigation of the association between a non-ionic microemulsio...
Antunes, Filipe E.; Thuresson, Krister; Lindman, Björn; Miguel, Maria G.Hydrophobically modified polymers (HM-P) typically behave as thickeners in a wide range of systems. The thickening effect in an aqueous solution of this kind of polymer depends on intermolecular hydrophobic associations and also on chain entanglements if the polymer concentration is significantly above the overlap concentration. In the present investigation a rather short end-capped polymer has been investigate...
