Morphology and mechanichal properties of Polyacrylonitrile (PAN) Multi Walled Carbon Nanotube (MWNT) nanocomposite electrospun fibers

The morphology and mechanical properties of PAN-MWNTs fibers were studied here. The electrospinning process was used to produce fiber in micro and nanoscale. Dispersion of MWNTs in polymer solution is the key factor to obtain good results in final product, so its condition was investigated using solvent film SEM images. The morphological study in fiber mat showed that by increasing the amount of MWNTs in polymer from 0 to 1%, the surface roughness of fibers was affected. In mechanical characterization it was observed, increasing the percentage of MWNTs in fiber improved this properties about 50% in fiber mat.
