Barrier and physicochemical properties of structured cellulose materials

Treesearch research themes:

Structured cellulose materials can form quite dense structures, which then yields high gas barrier properties. This has been shown for e.g. cellulose nanofibrillar films. The reason is most probably that these fibrils arranges them self side-by-side locally to the extent that it is often difficult to distinguish individual fibrils in the solidified films.  In this project a more systematic study where the oxygen and moisture barrier and physicochemical properties will be correlated with the morphology of differently structured cellulose-based materials.
