  1. 1. Swelling and Microstructure of Nanoplatelet Systems

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

    Sammanfattning : 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. LÄS MER

  2. 2. Swelling of Cellulose Fibrillar Matrices and Gels

    Författare :Pernilla Karlsson; Lars Wågberg; Per Tomas Larsson; Eero Kontturi; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swelling; hydrogel; cellulose; wood; cellulose fibrils; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : One of the major challenges of today´s society is to find a sustainable way to create a living based on the resources on earth. It is a challenge that includes a transition from fossil-based materials to renewable/biodegradable raw materials and also the creation of an environmentally friendly circular material flow. LÄS MER

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

    Författare :Janis Ritums; KTH; []
    Nyckelord :diffusion; swelling; mechanical properties; polymers;

    Sammanfattning : 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. LÄS MER

  5. 5. Polymer Gels: Modeling the Swelling Behavior

    Författare :Stefanie Schneider; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 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;

    Sammanfattning : 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. LÄS MER
