Abstract
Nanoscaled cellulosic materials have an inherent tendency
to form films upon drying. These films have unique
physical properties: they are strong and they can appear
as translucent or even fully transparent depending on the
overall dimensions of the individual fibrils. They
possess good thermal stability, smoothness, density and
chemical reactivity which make them as attractive
templates for bioinspired functional materials. The
characteristic features discussed will be the mechanical
behaviour, surface roughness and reactivity of
nanofibrillated cellulose films. The larger attention is
paid not only for the films' ability to act as oxygen and
moisture barriers but also for their peculiar behaviour
in the presence of water molecules. Few relevant
approaches to control the water sensitivity of the films
are discussed. These include direct chemical modification
and atomic layer deposition (ALD) performed on the
nanocellulose film. These combinations create films with
very low oxygen permeability values also at relative
humidities as high as RH80%
