Polymers nanocomposites made from polystyrene, 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 physcial. The fabricated nanofibers became hydrophilic in groups of (14,16 wt.%) and hydrophobic in group of (12wt.%) polystyrene concentration, also, when added natural dye to the group of (12wt.% PS) the fabricated nanofibers became more hydrophobic the other groups. The energy bandgap was improved and decreased when natural dye was added to about (0.2ev). the prepared samples can be used in many sensors applications such as optical sensing through the results taken from the UV-Visible (Q,K,Abs.,Bg) calculations.
