  2. 1. Polymer Gels: Modeling the Swelling Behavior

    Author : Stefanie Schneider; Fysikalisk kemi; []
    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

  4. 2. Swelling and Microstructure of Nanoplatelet Systems

    Author : Axel Thuresson; Beräkningskemi; []
    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

  5. 3. Synchrotron X-ray Scattering and Monte Carlo Simulations of Structure and Forces in Silicate Nanoplatelet Dispersions

    Author : Mo Segad; Beräkningskemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAXS; MC simulations; Swelling; Tactoids; EXAFS; DLS; Cryo-TEM; Nanoplatelets; MX80; Na Ca montmorillonite.;

    Abstract : Clays are the world’s most widely used natural material, however, little is known regarding the microstructure as well as the forces involved in clay-water interactions, and their influence on the swelling properties. The utilization of clay platelets is nowadays a key in a number of biological and industrial applications e.g. READ MORE

  6. 4. Chemical Pathways to Electrically Conductive Hemicellulose Hydrogels

    Author : Weifeng Zhao; Ann-Chiristine Albertsson; Ulrica Edlund; Karin Odelius; Elisabet Brännvall; Peter Plikk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrically conductive; hemicellulose; hydrogels; swelling behavior; aniline oligomers; renewable; polymer synthesis; Elektriskt ledande; hemicellulosa; hydrogel; svällning; anilinoligomerer; förnyelsebar; polymersyntes; Kemi; Chemistry;

    Abstract : Hydrogels have been extensively explored and are widely used in diverse biomedical applications, such as scaffolds for tissue engineering and vehicles for drug delivery. As one type of important natural polymer-based hydrogel, hemicellulose hydrogels have interesting attributes, including being renewable, non-toxic, biocompatible, biodegradable, and abundantly available.
