Abstract
Thin (25 nm) and highly uniform Al2O3 coatings have been
deposited at relatively low temperature of 80 and 100 °C
onto various bio-based polymeric materials employing the
atomic layer deposition (ALD) technique. The work
demonstrates that the ALD-grown Al2O3 coating
significantly enhances the oxygen and water vapor barrier
performance of these materials. Promising barrier
properties were revealed for polylactide-coated board,
hemicellulose-coated board as well as various biopolymer
(polylactide, pectin and nano-fibrillated cellulose)
films.
