POLYAMIDE COMPOSITES CONTAINING GRAPHENE OXIDE SHEETS

摘要

Graphene oxide/polyamide compositions are provided, as are methods for making and using the compositions. The graphene oxide component of the compositions has a C:O ratio of between 3 and 20, and comprises 0.01% to 5.0% by weight of the composition. Typical polyamide components include specialty nylons such as PA-11 and PA-12. The compositions have reduced water absorption and enhanced durability relative to otherwise identical polyamide compositions lacking the graphene oxide component. The compositions are particularly useful, for example, in flexible pipes and tubes used for transporting oil and gas.
