The article studied Eisenberg model, Forsman model, Dreyfus model, Bonnoto Bonner, Longworth, Vaughan model and Core-shell model. A BAB-triblock copolymer was employed as macromolecular model. Minimized Gibbs free energy relates the micellar structure parameters to parameters of the triblock copolymer quantitatively. Furthermore, it could be explained theoretically that the micellar diameter and the equilibrium aggregation number both decrease with ion content.
