A barrier material comprising a reduced graphene oxide laminate membrane; wherein the reduced graphene oxide laminate membrane has a water permeability below 10- 4 g/m 2/day at 100% RH and room temperature. Previously presented
The barrier material of claim 24, further comprising an oxidised polymer substrate. Previously presented
The barrier material of claim 24, wherein the reduced graphene oxide is formed from the reduction of graphene oxide with a reducing agent which does not generate significant amounts of C 0 2 or CO as a major component when it reduces graphene oxide; and/o r wherein reduction of the graphene oxide with the reducing agent leads to the oxygen originating from the graphene oxide which is displaced being substantially or exclusively expelled as water. Previously presented
The barrier material of claim 24, wherein the reducing agent is one or more selected from the group consisting of: HI, HB r and ascorbic acid (vitamin C). Previously presented
The barrier material of claim 24, wherein the reduced graphene oxide laminate membrane is supported on a substrate. Previously presented
The barrier material of claim 24, wherein a cross-linking agent is interspersed throughout the reduced graphene oxide laminate. Previously presented
The barrier material of claim 24, wherein the reduced graphene oxide laminate membrane has a water permeability below 10-6 g/m 2/day at 100 % RH and room temperature. Previously presented
The barrier material of claim 24, wherein the reduced graphene oxide membrane is affixed to a metal substrate and an adhesion promoter is dispersed throughout the reduced graphene oxide laminate and/or or between the reduced graphene oxide laminate and the substrate. Previously presented
The barrier material of claim 24, wherein the reduced graphene oxide membrane is affixed to a glass or silicon based substrate and an adhesion promoter is dispersed throughout the reduced graphene oxide laminate and/or or between the reduced graphene oxide laminate and the substrate Previously presented
