Composite nanofibers of Poly(Trimethylene terephthalate) (PTT)/single walled-carbon nanotubes (SWCNTs) were prepared by electrospinning technique in the form of a random fibers web.
Morphology, crystallinity, and mechanical properties of the electrospun composite nanofibers were investigated by SEM, DSC, and tensile testing, respectively.
SEM observations indicated that the presence of SWCNTs resulted in finer nanofibers for lower loading; however, a broader diameter was found for nanofibers with higher amounts of carbon nanotubes. It was also observed that the melt-crystallization temperature of PTT nanofibers shifted to a higher temperature by the incorporation of SWCNTs which might be due to the nucleating effect of the nanotubes. The mechanical properties (specific strength and modulus) of the PTT nanofibers were significantly enhanced by the incorporation of SWCNTs.
