Hydrophobically cross-linked micellar solutions : microstructure and properties of the solutions

Abstract

solutions that contained microemulsion droplets. It was found that the viscosity of these solutions could become significantly enhanced upon its addition. SANS and light scattering data of these solutions showed that the size of the droplets did not change. The scattering data of the cross -linked micelles could be fitted with a model for hard spheres that induded an additional attractive term. The shear moduli which were determined from the viscoelastic solutions are consistent with the scattering data.

Investigation of Effect of Adding Hydrophobically Modified Water Soluble Polymers on the Structure and Viscosity of Anionic Vesicle Dispersion

“…The volume fraction depends on the molar concentration of the vesicle dispersions. This has been similarly observed in the case of enhancing the viscosity of microemulsions by the addition of hydrophobically end-capped polymers [25]. The mean spacing between the bilayers of the vesicles db is equal to d-2R.…”

Macroscopic properties and microstructure of HSA based organogels: Sensitivity to polar additives

“…The scaling is for both cases relatively similar and only slightly more concentration dependent for the case of ethylene glycol. From a simple network theory [27][28][29] one can relate the shear modulus G 0 (that in our case should be well approximated by G (1 Hz)) directly to the number of network points by:…”

One-step RAFT synthesis of well-defined amphiphilic star polymers and their self-assembly in aqueous solution

“…It was found that these polymers form a transient network of interconnected micelles in water. [1][2][3][4]8,[10][11][12][13][14][15] The hydrophobic end groups function as ''stickers'' and the viscosity increase can be correlated to their length. 1,4,8,13,15 In the case of linear polymers, it is obvious that one polymer molecule can link not more than two micelles.…”
