  1. 1. Deformation of cellulose allomorphs studied by molecular dynamics

    Författare :Cyrus Djahedi; Lars Berglund; Stefan Lundmark; Margareta Åkerholm; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Polymer; Molecular Dynamics; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose-based materials draw their good mechanical properties from the cellu-lose crystal. Improved understanding of crystal properties could lead to a wider range of applications for cellulose-based materials, Cellulose crystals show high axial Youngs modulus. LÄS MER

    Sammanfattning : The primary cell wall is a complex multipolymer system whose composite structure has been mostly determined from chemical and biochemical studies. Although the primary cell wall serves a central role, with regard to the connective properties of fibres, knowledge about the interactions among the polymers, when it comes to the mechanical properties, is very limited.
