Abstract
A fluid transport tube and method for forming including either of a monolayer or multiple layers and having a polymer or copolymer which is formed into a circular cross sectional profile and with a Graphene material included in the layer. The Graphene material further includes any graphene derivative not limited to single layer Graphene, few layered Graphene, Graphene oxide and reduced Graphene oxide. Versions of the tube can further include inner and outer layers, between which at least one barrier layer is provided. Any of a polyamide 12 (PA 12) or polyamide 612 (PA 612) can be incorporated into the layer for increased environmental barrier resistance.
