Crystalline and tensile properties of carbon nanotube and graphene reinforced polyamide 12 fibers

► PA12 fibers spun with carbon nanotube and graphene nanoplatelet as additives. ► The nanofillers act as nucleating agents causing an increase in the crystallinity of PA12. ► Nanofillers significantly reinforces the fibers improving mechanical properties. ► Comparison made between reinforcing capabilities of carbon nanotube and graphene nanoplatelets.
