Nanoscale Supramolecular Structures in the Gels of Poly(Diallyldimethylammonium Chloride) Interacting with Sodium Dodecyl Sulfate

Abstract: A highly ordered supramolecular structure is formed in the polyelectrolyte-surfactant complex between the anionic surfactant sodium dodecyl sulfate (SDS) and the cationic network of poly(diallyldimethylammonium chloride) (PDADMACl). From small-angle X-ray scattering (SAXS), the complexes between PDADMACl and SDS were shown to exhibit a hexagonal type of microstructure which is different from that of pure SDS. A d spacing of 3.7 nm corresponding to the interdistance between SDS aggregates in the gel network was… Show more

“…Surfactant molecules easily penetrate a gel due to hydrophobic interactions and form complexes with the polyelectrolyte charged groups. At the same time, surfactant molecules selfassemble within the gel, and their ordering even exceeds the ordering of surfactants in solutions, as was reported in a number of publications [8][9][10][11][12]. Since a polyelectrolyte gel-surfactant complex contains counterions in well-ordered surfactant areas within a weakly crosslinked gel, these counterions can be replaced with ions of interest (transition metal ions).…”

“…Another suitable Co source is Co 2 (CO) 8 . Despite the fact that this compound is well-soluble in toluene, its preferable incorporation into the micelle core occurs due to formation of cationic-anionic complexes involving 4-VP units [38].…”

“…In our laboratory, a synchrotron X-ray source has been used to investigate the structures of poly(diallyldimethylammonium chloride-coacrylamide) [P(DADMACl/AM)] gel-sodium alkylsulfate (SC n S) complexes. 7,11 The complexes showed structures of cylindrical hexagonal at n Ն 12, and cubic at n Յ 10, respectively. However, the cubic structure was not analyzed, and the desired charge contents of the copolymer chains were not obtained due to the large difference in the reactivity ratio between the two comonomers.…”

“…In addition, it was reported that a thermosensitive gel could also be prepared as a result of binding of the cationic surfactant, tetraphenylphosphonium chloride, to a negatively charged polyelectrolyte gel, poly[2-(acrylamido)-2-methylpropanesulfonic acid] 16) . Guided by work [17][18][19] devoted to the interactions of polyelectrolyte gels with surfactants we studied the swelling and collapse of poly(diallyldimethylammonium chloride) (PDADMACl) hydrogels in the solution of an anionic surfactant, sodium dodecyl sulfate (SDS), and found that this system can undergo a continuous volume phase transition upon heating at some specific conditions.…”
