Strength and barrier enhancement of paperboards properties with cellulose nanofibrils applied by blade coater

摘要

1 Cellulose nanofibrils (CNF) are biodegradable, renewable with higher specific surface area and strength. 2 CNF show some potential to improve coated paper properties either as an additive in a coating or as a coating itself. 3 However, CNF at moderate solids has high viscosities. The best method to apply these high viscosities coatings is not clear.
