Polymers nanocomposites made from polysyrene, multiwall carbon nanotubes and natural dye using electrospinning technique to form nanocomposites nanofibers. The prepared samples were tested with different optical, morphological, topological and chemical tests to find the effect of adding fillers on above mentioned properties of polystyrene nanofibers the results proved that The viscosity of solutions increased with increasing polymer concentration, it decreased when adding MWCNT and slightly increased when adding the natural dye. The interaction between components is physical. The fabricated...
