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%
