  1. 1. Swelling and Microstructure of Nanoplatelet Systems

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Theoretical Chemistry

    Author : Axel Thuresson; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanoplatelets; Model clay system; Coarse grained models; Statistical mechanics; MC simulations; MD simulations; SAXS; Cryo-TEM; Laponite; Montmorillonite; Swelling; Tactoid;

    Abstract : Many clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. READ MORE

  4. 4. Diffusion, Swelling and Mechanical Properties of Polymers

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Janis Ritums; [2004]
    Keywords : diffusion; swelling; mechanical properties; polymers;

    Abstract : Polymers capability to withstand harmful interactions withdifferent environments can be determined by looking at thetransport and mechanical properties of the material exposed tothe medium. The diffusion of a penetrant in a polymer and itsswelling characteristics can be verified by a simplesorption-desorption experiment followed by methodical analysisof the data. READ MORE

  5. 5. Polymer Gels: Modeling the Swelling Behavior

    University dissertation from Physical Chemistry 1, Lund University

    Author : Stefanie Schneider; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Polymerteknik; biopolymers; Polymer technology; binding isotherms; polyelectrolyte-surfactant interactions; discontinuous volume transition; gel swelling; Monte Carlo simulation; polyelectrolyte gels;

    Abstract : This thesis is concerned with the swelling behavior of polyelectrolyte gels. The thesis can be divided into two parts. Part one deals with the modeling and computer simulation of the gel swelling. READ MORE
