    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.

    Sammanfattning : There is an increasing interest to replace fossil-based materials with renewable alternatives. Cellulose fibers/nanofibrils (CNF) are sustainable options since they are biobased and biodegradable. In addition, they combine low weight with high strength; making them suitable to, for example, reinforce composites. LÄS MER

  4. 3. Hemicellulose-based wood adhesives

    Författare :Tijana Todorovic; Eva Malmström; Linda Fogelström; Francisco Vilaplana; Magdalena Sterley; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The increasing sustainability concern encourages the society to use sustainable resources. In the wood industry the main component is from a renewable resource, but others are not. One of the fossil-based components is the adhesive. LÄS MER

  5. 4. Polysaccharide-based wood adhesives

    Författare :Tijana Todorovic; Eva Malmström; Linda Fogelström; Johannes Konnerth; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : It is highly desirable to increase the use of renewable resources and reduce fossil-dependence due to sustainability concerns. As a consequence, it is expected that the use of the wood-based materials will increase in the future. Therefore, adhesives will have an important role since they allow for the use of lower-quality and recycled wood. LÄS MER
