Abstract
We present a simple model to study micellization of amphiphiles condensed on a rod-like
polyion. Although the mean ˙eld theory leads to a ˙rst order micellization transition for su -
ciently strong hydrophobic interactions, the simulations show that no such thermodynamic phase
transition exists. Instead, the correlations between the condensed amphiphiles can result in a
structure formation very similar to micelles. c 2001 Elsevier Science B.V. All rights reserved.
