  2. 2. Polyelectrolyte - Surfactant Interactions in Dilute Suspensions. A Study Based on Monte Carlo simulations and Mean-Field Calcultations

    Author : Torsten Wallin; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aggregation number; linear charge density; chain flexibility; mean-field; calculation; simulation; Monte Carlo; cmc; cac; interaction; electrostatic; charged; micelle; polyelectrolyte; surfactant; hydrophilic; hydrophobic; Physical chemistry; Fysikalisk kemi;

    Abstract : The complexation of macroions or charged micelles and oppositely charged polyelectrolytes was studied by the use of Monte-Carlo simulations and mean field calculations. The Monte-Carlo simulations were performed on a simple model system with the emphasis on the electrostatic interaction, (i) polyelectrolyte rigidity, (ii) polyelectrolyte linear charge density, (iii) surfactant tail length, and (iv) the polyelectrolyte concentration.

  3. 3. Surface force studies of association phenomena at solid-liquid interfaces

    Author : Andra Dedinaite; KTH; []
    Keywords : ;

    Abstract : The main topics of this thesis, association phenomena inbulk and at solid-liquid interfaces in polar and non-polarmedia, were studied by a range of methods. Direct forcemeasurements employing the interferometric surface forceapparatus (SFA) was the chief technique. READ MORE
