Magnetic Surfactants

Magnetic surfactants are molecules that have transition metal elements as part of their molecular structure. Unlike magnetic-fluids developed in the previous century, the paramagnetic properties of the liquid phases of magnetic surfactants do not depend on the suspension of metal particles. Our work focuses on surfactants with a magnetic moiety being either covalently attached to the surfactant or incorporates as a magnetic counterion. Ongoing studies include the synthesis of novel magnetic species with multiple magnetic moieties per surfactant, the characterization of the surfactant behavior inside and outside an applied magnetic field, and the application of the magnetic surfactants for magnetically-induced separation processes.
