THE KRAFFT TEMPERATURE OF SURFACTANT SOLUTIONS

Abstract

Our main motivation to revisit the solution properties of cetyltrimethylammonium romide is related to the clear requirement for better control of the adsorption arameters to form uniform self-assembled monolayers on muscovite mica ubstrates. To readily monitor the temporal evolution of structural details in etyltrimethylammonium bromide solutions, we realized a rather simple onductivity experiment. Conductivity measurements were carried out as a unction of temperature, to look closer into the Krafft temperature behavior of his surfactant. We measured the electrical conductivity of different oncentrations of aqueous cetyltrimethylammonium bromide solutions, below nd above the critical micells concentration.
