Modeling the Self-Aggregation of Small AOT Reverse Micelles from First-Principles

Abstract

This Letter is the first attempt at studying the self-aggregation of AOT reverse micelles from first-principles. It focuses on predicting the aggregation number, the radius of gyration, and the hydrodynamic radius of a low water content reverse micelle by theoretical means. We show that molecular dynamics simulation in the μs time range combined with atomistic potentials is capable of reproducing and explaining, to a convenient degree, experimental results on the size and dimensions of reverse micelles of AOT of low water content, [H2O]/[AOT] ≈ 5.
