An air-impermeable fabric is disclosed. The air-impermeable fabric has a fabric substrate, which may also be referred to as a base fabric. Disposed over the fabric substrate is a barrier layer comprising a polymer binder and at least 20 weight percent graphene nanoplatelets, based on the total weight of the barrier layer. A barrier underlayer, which may or may not also include graphene nanoplatelets, is disposed between the fabric substrate and the barrier layer. A barrier overlayer, which may or may not also include graphene nanoplatelets, is disposed on the opposite side of the barrier layer from the barrier underlayer. |
