High potential of cellulose nanofibrils for technical applications

• Cellulose nanofibrils could be very useful for an application in waterborne coatings or adhesives to improve hardness, cohesive and adhesive strength, stiffness, exploitation or thermal creep. Application developments in electronics (LCD panels) where the transparency of cellulose nanocomposites could be used or in nanopapers for filters and membranes are also conceivable. A challenge is the combination of cellulose fibrils with natural polymers. Extensive applications in medicine, food, packaging or transportation are conceivable. Possible raw materials are polymers like poly lactic acid (PLA). To expand the use of bio-based nanocomposites for high-value applications, it is necessary to avoid the reagglomeration and internal entanglement of cellulose fibrils and to improve their homogeneous dispersion in hydrophobic polymers. Special research emphasis is therefore given to the appropriate chemical modification of cellulose nanofibrils. An overview of the high application potential of cellulose nanofibrils with respect to own product development activities will be presented.
