1. 1. A Waterborne Colloidal Model System Consisting of Fluorinated Spheres Bearing Grafted PEG: Synthesis, Characterization and Properties

   Författare :Jeanette Ulama; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colloidal model system; steric stabilization; core-shell; poly ethylene glycol PEG ; heptafluorobutyl methactylate HFBMA ; fluorinated; polymer; phase behavior; short-range attractions; semi-batch emulsion polymerization; small angle X-ray scattering SAXS ; smearing effects; dynamic light scattering DLS ; cryogenic-transmission electron microscopy cryo-TEM ;

   Sammanfattning : Model systems have expanded our knowledge of numerous phenomena in Colloid Science, such as the appearance of glasses, order-disorder transitions involving crystals and attraction induced formation of gels. So far, the existing colloidal model systems have been limited mainly to nonaqueous media. LÄS MER

3. 2. Structure, phase behavior, and dynamics of colloidal systems characterized by strong, short- and moderate-ranged attractions: a computational study

   Författare :Bodil Ahlström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Attractions between colloidal particles are often so strong that non-equilibrium behavior results. However, dissolved non-adsorbing polymer can be added to give a weak attraction between particles so that equilibrium phase transitions appear at moderate polymer concentrations. LÄS MER
