  3. 2. 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

  4. 3. Polymer Nanocomposites in Thin Film Applications

    Författare :Linda Fogelström; Anders Hult; José M. Kenny; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocomposites; hyperbranched polymers; montmorillonite; clay nanoparticles; exfoliated; coatings; crosslinking; TEM; XRD; mechanical properties; thermal properties; cellulose nanofibers; Atom Transfer Radical Polymerization; Ring-Opening Polymerization; poly ε-caprolactone ; surface modification; grafting; interfacial adhesion; Polymer chemistry; Polymerkemi;

    Sammanfattning : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.
