  1. 1. Multifunctional silk: from fabrication to application

    Författare :Manish Singh; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silk; Sonochemistry; Supercritical impregnation; Nanofiller; Soft biosensor; Enzyme mimic;

    Sammanfattning : Silk fibers offer untapped internal structures to template the formation of nano-objects and active coatings. So far, access to all or part of the internal and organized structures has been a significant challenge. LÄS MER

  3. 2. Carbon nanofiller reinforced UHMWPE for orthopaedic applications : optimization of manufacturing parameters

    Författare :Evelina Enqvist; Mats Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Polymer composites research designed for orthopaedic applications are commonly focused on Ultra high molecular weight polyethylene (UHMWPE) reinforced by a variety of different nanoparticles. However, the high melt viscosity of UHMWPE renders conventional melt mixing techniques impossible for composite manufacturing. LÄS MER

  4. 3. Structural and Physical Effects of Carbon Nanofillers in Thermoplastic and Thermosetting Polymer Systems

    Författare :Sanjukta Chatterjee; Svensson Svante; Ritva Serimaa; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer; Composite; Carbon nanotube; Graphene;

    Sammanfattning : Ever since the discovery of carbon nano materials like carbon nanotube (CNT) and graphene, this class of materials has gained significant attention due to their exotic properties. The principle idea of my present research project is to understand the novel improvements induced in polymer matrices with inclusion of the nanofillers. LÄS MER

  5. 4. 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.
