Electrospinning Polymer Nanocomposites for High Sensitive Applications

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 nanofibers became hydrophilic in groups of (14, 16 wt.%) and hydrophobic in group of (12wt.%) polystyrene, also when added natural dye to the group of (12wt.% ps). The fabricated nanofibers became hydrophilic in groups of (14, 16 wt.%) and hydrophobic in group of (12wt.%) polystyrene, also when added natural dye to the group of (12wt.% ps). The energy bandgap improved when natural pigment was added to the group (12 wt.%) and give us a value (0.2 ev). Prepared samples can be used as optical sensors from the results of UV-Visible parameters (¿, n, k, Abs., Bg).
