In this research, the effect of incorporation modified Silicon carbide (SiC) nanoparticles on morphological and mechanical properties of electrospun nanofibers were studied. Due to inorganic nature of SiC nanoparticles there is no good interaction between organic nanofibers and inorganic nanoparticles leading to poor nanoparticle dispersion. Therefore, the SiC nanoparticles were chemically modified to be compatible with polyacrylonitrile (PAN) nanofibers. Afterwards, modified SiC nanoparticles were incorporated into the PAN solutions (in several concentrations) and the nanofibers were then prepared via electrospinning technique. The morphology of the nanofibers were investigated by scanning electron microscopy (SEM). The tensile tests were carried out to assess the tensile properties of the prepared nanofibers. Morphological investigations of the nanofibers showed that after incorporation 3 wt% modified SiC nanoparticles the average diameter of the nanofibers increased to 388 nanometres which possibly attributed to decrease in solution conductivity due to nanoparticle modification. In addition, evaluation of the tensile properties of the nanofibers web with modified SiC nanoparticles showed that the tensile strength of the nanofibers 188% improved after incorporation of 3% modified SiC nanoparticles.
