Micelle Fromherz model

Figure 3 A possible cross-sectional view of the Fromherz micelle. This model is constructed using cylindrical sticks to represent the surfactant molecules. Counterions are not shown. (From Ref. 2 with permission.)...

Fromherz s model considers a spherical micelle where the surfactants are arranged in parallel forming a packaging without tensions and without contact with the water, in which the heads of the surfactants are as separated as possible [20], The surfactant chains, in the region of the heads, are bent to lower electrostatic repulsion as much as possible. Figure 3 shows a cross-section of this model of micelle. 

The models of Fromherz and Dill allow the solubilization of hydrophobic solutes near the surface of the micelle and explain how these solutes (in addition to part of the hydrocarbon chains of the surfactants) can be in contact with the water when they are associated with the micelle. However, the debate concerning the structure of the clusters is not yet finished and research on the subject continues.

The standard picture of ionic micelles forms a common starting point for three recent attempts at modelling the state of the chains in amphiphilic aggregates Dill and Flory s lattice model [15, 16], Fromherz surfactant-block model [18] and a model devised by the present author [19-21]. For each of these models, it is necessary to make further assumptions which are not part of the standard picture. These further assumptions are necessary in order to render the models soluble.
