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
