“…Self-organization was shown to occur from nano-to macroscopic length scale resulting in formation of various soluble and insoluble surfactant-polymer complexes (PSC) [1][2][3][4][5][6][7][8][9][10]. Substantial efforts have been made to clarify their structures, especially those in the solid state, because PSC represent a new and very interesting class of assembled materials [11].…”

Structural characteristics and thermal stability of a series of dodecylammonium carrageenates formed by stoichiometric complexation of dodecylammonium chloride and differently charged carrageenans (κ-, ι-and -carrageenan, respectively) were investigated. IR spectral analysis confirmed the electrostatic and hydrogen bond interactions between the dodecylammonium and carrageenan species. X-ray diffraction experiments show increased ordering in the complexes compared to that in the parent carrageenans. Dodecylammonium carrageenates have a layer structure, in which a polar sublayer contains layers of carrageenan chains and a nonpolar sublayer consists of conformationally disordered dodecylammonium chains electrostatically attached to the carrageenan backbone. The major factor that determines the dodecylammonium carrageenate structure is cationic surfactant, while the carrageenans moiety plays a major role in determining thermal properties.

“…In other words, surface tension, turbidity, and viscosity of polymer-surfactant solutions were investigated. With advances in analytical modern technology such as cryo-TEM and X-rays, the complex of polymer with surfactant has been found to be a liquid crystal such as a bilayer or vesicle [4].…”

“…The polyelectrolyte can interact electrostatically with the polar head of an oppositely charged surfactant, and the hydrophobic interactions among nonpolar segments of the bound surfactant molecules promote their aggregation. It is well established that this aggregation is stabilized in the presence of polyelectrolyte and starts at a surfactant concentration (critical aggregation concentration, cac) much lower than its critical micellar concentration (cmc) [25][26][27][28][29][30] . When the polyelectrolyte has also hydrophobic moieties (amphiphilic polyelectrolyte), it can strongly bind an oppositely charged surfactant, by both electrostatic and hydrophobic forces, promoting the formation of mixed micelles [31,32] .…”
