    Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

  4. 2. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    Author : Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE

  5. 3. Hygro- and hydroexpansion of paper : Influence of fibre-joint formation and fibre sorptivity

    Author : Per A. Larsson; Lars Wågberg; Kaarlo Niskanen; KTH; []
    Keywords : ;

    Abstract : Paper is a versatile, cheap and environment-friendly material. Nevertheless, there are several factors limiting its usefulness, and one of the major issues is that cellulosic and ligno-cellulosic fibres spontaneously sorb water. At the same time, the water uptake changes the dimensions of the paper. READ MORE
