  1. 1. Swelling and Mechanical Properties of Polymer Gels: Salt, Macroion and Network Topology Effects

    Author : Samuel Edgecombe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; volume decrease upon uniaxial extension; interpenetrating networks; loose-end effects; polydispersity effects; macroion deswelling; salt deswelling; polymer gels; polyelectrolyte gels; Physical chemistry; Fysikalisk kemi;

    Abstract : The work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. READ MORE

  2. 2. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Author : Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Abstract : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. READ MORE

  3. 3. Interaction Between Microgels and Oppositely Charged Peptides

    Author : Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Abstract : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. READ MORE
