Abstract

In this research the morphology and mechanical properties of PAN/MWNTs nano bers are
studied. The electrospinning process is used to produce ber at micro and nano scale. The dispersion of
MWNTs in polymer solution is the key factor to obtain desirable properties in the nal product. Thus,
the dispersion condition is investigated using SEM images. The morphological study of ber mats show
that by increasing the amount of MWNTs in the polymer from 0 to 1 wt%, the surface roughness of bers
is increased. Increasing the percentage of MWNTs in ber improves the tensile stress at maximum load
for about 114% and modulus for about 40%.
