  7. 25. Laser Scattering for Fast Characterization of Cellulose Filaments

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
    Nyckelord :Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

    Sammanfattning : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.
