  1. 6. Wet spinning of carbon fiber precursors from cellulose-lignin blends in a cold NaOH(aq) solvent system

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Landmér Alice; [2022]
    Keywords : Carbon fiber; cellulose; cold NaOH aq ; lignin; precursor; sodium hydroxide; solution spinning; wet spinning;

    Abstract : Carbon fiber (CF) is predominantly produced from fossil-based sources and is therefore an area of interest for further development towards a more sustainable society. The purpose of this thesis work was to investigate the possibility of producing precursor fibers (PFs) for CF production from a blend of renewable cellulose andlignin. READ MORE

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

    University essay from KTH/Fiber- och polymerteknologi

    Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
    Keywords : 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;

    Abstract : 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.

  4. 8. Mycelium: Growing materialsexperience : A study on improving the appearance of mycelium-composites through a material driven design process

    University essay from Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

    Author : Frida Andersson; [2022]
    Keywords : Mycelium; Product Design;

    Abstract : Mycelium-composites has been emerging commercially as an environmentally sustainable alternative to conventional materials. By utilizing the fungal mycelium’s ability to bond with lignin and cellulose fibers of plants, mycelium-composites can be made that are recyclable and renewable. READ MORE

  5. 9. The impact of interface characteristics on the recyclability and repulpability of packaging material

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Ingrid Isacsson; [2022]
    Keywords : Tetra Pak ®; Recyclability; repulpability; packaging material; fiber-based barrier; chemical engineering; Technology and Engineering;

    Abstract : The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. READ MORE

  6. 10. Enhancement of translucence in fiber-based packaging materials

    University essay from KTH/Fiber- och polymerteknologi

    Author : Saila Tallinen; [2022]
    Keywords : Paper; translucent; fiber-based packages; impregnation; cellulose; papper; genomskinlighet; fiberbaserade förpackningsmaterial; impregnering; cellulosa;

    Abstract : The utilization of fiber-based packages has started to take more place at the packaging sector but is still restricted by a lack of transparency. Today this challenge is tried to be solved by paying more attention on the characteristics of nanofibers and their possibilities. READ MORE
