Important results from the project

The literature, and partly our studies, shows that graphene has good possibilities to affect both the oxygen- and the water vapor permeability. Graphene can be used as larger sheets or as layers of homogenously distributed graphene flakes. The results are promising but some challenges remains regarding dispersion properties, quantification and robustness before a good packaging with a graphene barrier can be produced at a competitive price. An additional challenge is to find easy and good ways to apply graphene with existing equipment and infrastructure.

Expected long term effects

The knowledge that has been obtained in the project can serve as a basis for future larger research efforts on graphene in novel packaging and cellulose based material. The project has enabled that we now, in a more systematic way, can identify challenges that are needed to be met before usage of graphene as a barrier in packaging. The results are promising but there are some major challenges. The project has been presented at the Packbridge seminar and contacts have been made with industrial, academy and institutes partners.

Approach and implementation

The project started with a literature review and patent search. This review was presented on a project meeting and the findings served as a basis for discussions and experimental work. Initially, the dispersion properties of graphene were investigated. Then, extruded films and biobased coatings were produced and evaluated with microscopy and oxygen permeability measurements. A cost analysis was performed. The project has already been valuable to scientifically identify existing challenges, but to be able to reach pilot scale production, larger research projects are needed.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
