Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


After the course the student is able to

  • Tell the physical and chemical distinctions between natural fibres, regenerated fibres, and nanofibres
  • Describe the basic structures, properties and functions of common hemicelluloses and lignins
  • Master the morphology of the native cellulose microfibril and acknowledge how it affects nanocellulose preparation and properties
  • Explain comprehensively how nanocellulose is produced
  • Detect the major obstacles and difficulties in cellulose dissolution and regeneration through basic laws of physical chemistry
  • Explain the main pathways to chemical modification of cellulose and nanocellulose
  • Apply basic structure-property relationship to cellulose-based fibres and understand their implications in most common modern applications (excluding paper and board)
