2. 1. Tailoring fibre and paper properties using physical adsorption of polyelectrolytes

   Author : Andrew Marais; Lars Wågberg; Ulrica Edlund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The adsorption of polyelectrolytes, both as monolayers and as multilayers, was investigated as an easy and non-expensive way of producing lignocellulosic fibrous materials with enhanced mechanical properties.In the first part of the work described in this thesis, the adsorption of a polyelectrolyte monolayer onto the surface of unbleached and unbeaten kraft pulp fibres with different kappa numbers was investigated.

4. 2. Tailored cellulosic materials by physical adsorption of polyelectrolytes

   Author : Andrew Marais; Lars Wågberg; Andreas Fery; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The growing interest in using bio-based resources has made forest-based cellulose (used as fibre and nanofibril building elements) a good candidate for the development of new materials. In order to be used in commercial applications, cellulose must however be processed and/or functionalized to provide the final material with specific properties. READ MORE
