Descriptif
Acquaint the student with plant-based fibres and nanofibres: structure,
physical and chemical behavior as well as applications
Objectifs pédagogiques
- Knowledge and understanding - For a passing grade the student must :
- Be able to tell the physical and chemical distinctions between natural fibres, regenerated fibres, and nanofibres
- Be able to 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
- Be able to detect the major obstacles and difficulties in cellulose dissolution and regeneration through basic laws of physical chemistry
- Be able to explain the main pathways to chemical modification of cellulose, including nanocellulose
- Be able to apply basic structure-property relationship to cellulose-based fibres and understand their implications in most common modern applications
- Judgement and approach - For a passing grade the student must
- Be able to distinguish the special nature of plant-based fibres and assess how the properties affect their applicability
- Be able to point out the main bottlenecks in modern applications of cellulose-based fibres, and fibre components
- Be able to choose correct analytical methods for assessing certain properties of cellulose-based fibres and their applications
