The electrospinning method was used to organize nanofibers samples consisting of three teams, every group has a distinct polystyrene focus (12, 14, 16 wt.%). Multiwalled carbon nanotubes have been added to every group with 4 ratios to yield 4 samples comprising (polystyrene/MWCNT) constituents. The UV-Seen check was carried out to understand how uniformly nanofibers and Mutli-walled carbon nanotubes have been distributed within the polymeric nanofibers and their impact on the ultimate nanofiber’s properties by the absorption peaks. The morphological check used “Subject Emission Scanning Electron Microscope”. The outcomes confirmed that; MWCNTS has a dominant impact on ready nanofibers within the (12 wt.% Polystyrene) group, and each (PS, MWCNT) have a shared impact, highest regular absorption curves, and uniformly scattered radiation at (14 wt.% PS) group, and random outcomes at (16 wt.% PS) group. From FESEM outcomes we discover that growing polymer focus causes a rise within the nanofiber’s diameter and beads formation probability will increase at (12,16 wt.% PS) teams. Within the group of (14 wt.% Polystyrene), it produces nanofibers with free beads and uniform distribution, the addition of MWCNT lowers the diameter of nanofibers rather more and enhances the orientation, and improves their UV absorption, energy, and mechanical properties.
