文摘
- •
Colloidal dispersions crystallized thermoreversibly via ionic surfactant adsorption.
- •
The colloids crystallized on cooling and melted upon heating.
- •
The mechanism was studied by using polystyrene particles in ethylene glycol/water.
- •
The crystallization was caused by a decrease in the ionic strength of the medium.
- •
The present findings will be useful for fine control of colloidal crystallization.
