  1. 6. Solid Polymer Lithium-Ion Conducting Electrolytes for Structural Batteries

    Författare :Markus Willgert; Mats Johansson; Alexander Bismarck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This work comprises the manufacture and characterization of solid polymer lithium ion conducting electrolytes for structural batteries. In the study, polymer films are produced in situ via a rapid versatile UV irradiation polymerization route, in which ethylene oxide methacrylates are polymerized into thermoset networks. LÄS MER

  3. 7. Dendrimers and dendronized polymers : synthesis and characterization

    Författare :Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

    Sammanfattning : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. LÄS MER

  4. 8. A study of wood adhesion and interactions using DMTA

    Författare :Anna Backman Sandlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : The aim of the work presented in this thesis was to investigate whether the adhesion of glues and lacquers to wood could be studied using dynamic mechanical thermal analysis (DMTA). This method has been widely used to study interactions in polymer blends, copolymers and in polymeric composites but very few investigations had been done on solid wood. LÄS MER

  5. 9. Bio-based Composites from Soybean Oil Thermosets and Natural Fibers

    Författare :Kayode Adekunle; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bio-based thermoset resins; natural fibres; hybrid composites; renewable resources; mechanical analysis; compression molding; lyocell fiber; Energi och material; Resursåtervinning; Resource Recovery;

    Sammanfattning : In order to reduce over-dependency on fossil fuels and to create an environment that is free of non-degradable plastics, and most importantly to reduce greenhouse gas emission, bio-based products are being developed from renewable resources through intense research to substitute conventional petrochemical-based plastics with renewable alternatives and to replace synthetic fibers with natural fibers. Many authors have done quite a lot of work on synthesizing polymers from renewable origin. LÄS MER

  7. 10. Fabrication of polymeric microfluidic devices via photocurable liquid monomers

    Författare :Klas Tommy Haraldsson; Mats K. G. Johansson; Ken Carter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photopolymerization; radical photopolymerization; polymerization kinetics; photoinitiation; vinyl ether; maleate; vinyloxy; Polymer chemistry; Polymerkemi;

    Sammanfattning : Microfluidic devices have long been considered an ideal tool for rapid and inexpensive chemical analysis and reactions in areas ranging from point-of-care health to national security applications. However, fabricating microfluidic devices is time consuming, difficult and above all expensive. LÄS MER
