Continuous production of nanocellulose films with limited heating

The combination of our society’s drive towards a bio-based economy and legislation becoming stricter with regard to single-use plastics, nanocellulose films are predicted to be useful in a range of different fields, from biomedical and bio-based electronic applications to hygiene and packaging. Nanocellulose films are versatile and can be made to be either an active component or sensor, scaffolds and carriers of other materials/chemicals/pharmaceuticals, and/or a barrier when necessary.

However, continuous production of nanocellulose films is still a challenge, where one of the main technical difficulties is to remove water in an energy-efficient manner after the film is formed. It is possible to use heat to evaporate the water, however, heating is energy demanding and therefore expensive.

Here, we show that by suction and pressing it is possible to produce nanocellulose films from well dispersed carboxymethylated cellulose nanofibrils at 0.4 wt% in <20 min. The energy-consuming evaporation of water is limited and only used to remove the last water after the solids content has reached more than 20% solids. Lastly, a roll-to-roll process was designed and run at 1 m/min resulting in 10 cm wide films. We see this nanocellulose film production process as a platform that should be optimized depending on nanocellulose grade and final application.
