The average fibril diameter of CNFs may be related to the air resistance, oxygen barrier properties, and grease resistance. Hydrophobic functional groups with sufficient chain lengths decreased the water vapor barrier properties. CNFs with smaller fibril sizes are beneficial for enhancing barrier properties, and hydrophobization improves the water resistance. The average fibril size and hydrophobicity were strongly related to the barrier properties. A coat weight of at least 10 g/m 2 was desirable to impart efficient the barrier properties to papers. In this work, various types of CNFs were prepared and coated on linerboard and wood-free paper to evaluate the barrier properties of these papers against air, liquid water, water vapor, oxygen, and grease, and the major factors of the barrier performance of the CNFs-based coatings were investigated. ![]() Cellulose nanofibril (CNF) is considered an alternative to conventional polymers for barrier coatings due to the barrier properties of its films. Barrier paper packaging is in demand as environmentally-friendly barrier coating materials to improve biodegradability and recyclability. ![]() Needs for biodegradable packaging materials are growing to reduce the negative environmental impact of petroleum-based polymer packaging.
