Effect of fiber diameter on the deformation behavior of self-assembled carbon nanotube reinforced electrospun Polyamide 6,6 fibers

► CNT reinforced polyamide 6,6 fibers were fabricated using electrospinning. ► Effect of fiber size and the CNT content on tensile properties was characterized. ► The strength and modulus of fibers increased with reduction of fiber diameter. ► The presence of CNTs improved the strength and stiffness of the fibers.
