1. 1. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

   Författare :Jasna Stevanic Srndovic; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

   Sammanfattning : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

   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.
