摘要
An interesting observation reported that the critical micelle concentrations of an ionic amphiphilic block copolymer increased with the salt concentration. Numerical solutions of the Poisson-Boltzmann equations for polyelectrolyte brushes have suggested the existence of a region of approximately zero net charges close to the nonpolar core surface. The observed unusual salt effect could be explained if a kind of counter ion condensation is assumed in this region.
