Oxygen barrier coatings solely based on nanosize cellulose were developed.
•
The coating thickness varied from hundreds of nanometers for spin-coated layers, to micrometers for dip-coated ones.
•
Nanosize cellulose coatings showed better oxygen barrier than polymers such as PE and PS in dry conditions.
•
Thin nanocellulose coatings were sensitive for humidity and long term storage.
