This work related to fabrication of platinum nano particles, reveals considerably outstanding catalytic and electrical properties and preparation of Pt- PS nano composite. For this study Pt nano particles were synthesized by wet chemical method. Pt particles with 0.25%, 0.5%, 1% and 2% concentration amounts were added into the polystyrene solution, acquired by recycled PS. Three different composites which possess a distinct percentage of platinum were produced. Fibers were fabricated by electro spinning method afterward. Pt particles which were produced by wet chemical method and fibers were analyzed by SEM-EDS. There were various test and measurement methods performed to determine the characteristics of the platinum nano composite.
