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.

The dissolubility of PPLA in water was (2.16～4.32)×10－2 mg·mL－1 according to eye judgment. The critical micelle concentration was 2.16×10－2 mg·mL－1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.
