The aggregation of reverse micelles
- 27 Downloads
We have developed a computer simulation to model the formation of reverse micelles in two dimensions. Several of the qualitative results obtained from these calculations agree with experimental observations. Specifically, we have shown that the chain length has a large influence in determining the size and shape of the aggregate. We predict the existence of a critical tail length: Chains below this value will form an extended lamella-like structure, whereas chains longer than this value will form clusters that appear ellipsoid or circular in cross-section. Finally, we obtained a scaling law that relates the aggregation number (N) to the length of the tail (L):N∼L −1.14. A physical model to account for the observed exponent will be developed in a future paper.
