A synthetic barrier material comprising:
- light-cured photopolymer;
- and
- graphene nanoplatelets, wherein the graphene nanoplatelets are in substantially parallel alignment in the light-cured photopolymer,
- wherein the graphene nanoplatelet has a thickness in a range of 5-10 nanometers and a diameter in a range of 15-50 micrometers, and the synthetic barrier material has a graphene nanoplatelets content in the range of 1 to 5% by weight.
A method of manufacturing a synthetic barrier material, the synthetic barrier material comprising graphene nanoplatelets, wherein the method comprises:
- a) dispersing the graphene nanoplatelets in a photocurable resin;
- and
- b) applying an electric field to polarically align the graphene nanoplatelets in the photocurable resin, wherein the graphene nanoplatelets are in substantially parallel alignment in the photocurable resin;
- and
- c) applying a light source to cure the photocurable resin in which the graphene nanoplatelets have been dispersed and polarically aligned;
- wherein the graphene nanoplatelet has a thickness in a range of 1-5 nanometers and a diameter in a range of 1-15-50 micrometers, and the synthetic barrier material has a graphene nanoplatelets content in the range of 1 to 5% by weight.
