  2. 16. Highly-filled biocomposites: modelling, processing, and characterization

    Author : Sajjad Pashazadehgaznagh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; fiber orientation; rheology.; Wood plastic composites WPCs ; extrusion; surface instability;

    Abstract : The use of polymer with natural fiber reinforcements is expected to increase significantly. This can be noted in several industrial sectors of strategic importance for Sweden, such as automotive, packaging, construction, and furniture industries. READ MORE

  4. 17. Chemical Modification of Nanostructured Wood for Functional Biocomposites

    Author : Shennan Wang; Qi Zhou; Gustav Nyström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; nanostructured materials; nanocellulose; delignification; oxidation; crosslinking; amination; MOFs; transparent film; hydrogel; aerogel; biocomposites; mechanical properties; thermochromic materials; CO2 capture; protein immobilization.; Biotechnology; Bioteknologi;

    Abstract : Recently emerged top-down processing concept has provided new insights into the chemical modification of wood at the nanoscale. Nanostructured wood with naturally aligned cellulose microfibrils, cell wall nanoporosity, and precisely tuned chemical composition has opened up numerous possibilities for advanced design of functional materials.

  5. 18. Biofoams and Biocomposites based on Wheat Gluten Proteins

    Author : Qiong Wu; Mikael Hedenqvist; Richard Olsson; Hélène Angellier-Coussy; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheat gluten; biofoam; biocomposite; freeze-drying; flame-retardant; silica; antimicrobial; bimodal; conductive biofoam; flax fiber; crack-resistance; Kemi; Chemistry;

    Abstract : Novel uses of wheat gluten (WG) proteins, obtained e.g. as a coproduct from bio-ethanol production, are presented in this thesis. A flame-retardant foam was prepared via in-situ polymerization of hydrolyzed tetraethyl orthosilicate (TEOS) in a denatured WG matrix (Paper I). READ MORE

  6. 19. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose

    Author : Erfan Oliaei; Lars Berglund; Tom S. C. Lindström; Fredrik Berthold; ‪Maria Soledad Peresin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.
