Scattering from polymer-like micelles

Rheology of branched wormlike micelles

“…There is, however, no well-vetted quantitative rheological model for branched WLM solutions and so such deductions cannot, at present, be tested. A recent, comprehensive review of this field is contained in volume 140 of the CRC Surfactant Science Series, entitled "Giant Micelles, Properties and Applications" edited by Zana and Kaler [10], which, along with the aforementioned COCIS reviews [7,11], and a complementary review by Ezrahi et al [12], provides a basis of study for those interested in this field. Consequently, the scope of this review is a summary of the recent literature reports concerning the rheology of branched wormlike micelles, with emphasis on the past half decade.…”

Form factor for distorted semi-flexible polymer chains

“…with the innate persistence length l p as the characteristic length scale. For a distorted SFPC, (12) describes the persistence of the chain as long as Dl is smaller than the contour distance from the starting point to the next kink. When a kink occurs, the directional correlation is lost and K or (Dl) becomes zero.…”

“…1, a slight down bending away from the q À1 asymptote at high q indicates the onset of cross sectional effects. Scattering experiments have been used to characterize wormlike micelles, [5][6][7][8][9][10][11][12] bottle brushes, [13][14][15][16][17] and bio molecules. 18,19 Scattering experiments are indirect methods.…”

Dynamic and static radiation scattering in a microemulsion as a function of dispersed phase concentration

“…These association colloids have unusual characteristics due to its supramolecular structures resembling macromolecular coils (or rods, for lower aggregation numbers) [19,21]. Hence, some similarities between polymer and worm-like micelle solutions have been observed: e.g., a dependence of intrinsic viscosity/dynamic light scattering parameters on worm-like micelle dimensions [22][23][24], and a rheological behavior that, depending on experimental conditions (e.g.…”

“…Micellar systems based on C n E m may spontaneously form micelles with wormlike geometries [19,20]. These association colloids have unusual characteristics due to its supramolecular structures resembling macromolecular coils (or rods, for lower aggregation numbers) [19,21].…”
