Claims5
A biodegradable container comprising a biodegradable material and a reinforced barrier film coated onto the biodegradable material, wherein the reinforced barrier film comprises graphene nanoplatelets dispersed in a biodegradable polymeric substrate
- wherein the content of the polymeric substrate is 98%-99.9% by weight of the reinforced barrier film,
- wherein each of the graphene nanoplatelets has a diameter in the range of approximately 0.5 to 15 micrometres,
- wherein the graphene nanoplatelets comprises partially reduced graphene oxide mixed with exfoliated graphene flakes wherein the partially reduced graphene oxide has been obtained by thermal reduction at a temperature range of 150°-300° Celsius,
- and
- wherein the thickness of coating of the reinforced barrier film is in a range of 5 micrometres to 50 micrometres.
