  3. 2. Magnetic Ionic Liquids in Solutions and Emulsions

    University essay from KTH/Materialvetenskap

    Author : Simon Bruno; [2022]
    Keywords : ionic liquids; microemulsion; magnetic response; surfactant; co-surfactant; imidazolium cation; polarity; chain length effect; joniska vätskor; mikroemulsion; magnetisk respons; surfaktant; co-surfaktant; imidazoliumkatjon; polaritet; kedjelängdseffekt;

    Abstract : This research thesis reports experimental work done to design a stable magneticmicroemulsion of ionic liquid in 2-ethylhexyl laurate with the help of an ionic surfactant andan alcohol co-surfactant. The ionic liquids tested were based on a 1,3-dialkylimidazoliumcation with different alkyl chain lengths and a tetrachloroferrate anion ([FeCl4]+) to ensure theemulsion is sensitive to applied magnetic fields.
