Mesoscale simulations of surfactant dissolution and mesophase formation

TL;DR

This paper uses mesoscale simulations to study how surfactant dissolves and forms mesophases, revealing that mesophase formation quickly becomes diffusion-controlled and aligns with the equilibrium phase diagram within microseconds.

Contribution

It demonstrates that mesophase formation in surfactant-solvent systems occurs rapidly and follows equilibrium behavior shortly after initial contact, using mesoscale simulation techniques.

Findings

Mesophase formation becomes diffusion-controlled.

Formation follows the equilibrium phase diagram.

Process occurs within approximately 10 microseconds.

Abstract

The evolution of the contact zone between pure surfactant and solvent has been studied by mesoscale simulation. It is found that mesophase formation becomes diffusion controlled and follows the equilibrium phase diagram adiabatically almost as soon as individual mesophases can be identified, corresponding to times in real systems of order 10 microseconds.
