Polysaccharide films – formation and properties

Turning wood-based polymers and particles into films is vital for majority of their utilization (packaging, support materials) and for fundamental analytics (model surfaces for adsorption, interaction studies, strength characterization). Cellulose, hemicelluloses and lignins have distinct (from one another) intrinsic film formation behavior and properties that span from solubility, molecular weight and flexibility, and polarity. Main …

All wood cellulose films from flow

The project is on composites that comprise dominantly wood-based components. Fundamental endeavors are on orientation of cellulose nanomaterials and fibers in films. This is mediated via flow and shear. Cellulose body interactions are tuned by tuning particle surface characteristics. Rheology, crystallinity, strength and barrier performance are used to assess the products and the process. (part …
