Functional silver-polypropylene nanocomposite fibers are prepared?using melt-compounding and sputter coating techniques. The functional nanostructures?formed on the fiber surfaces are characterized by Atomic force microscopy.
The Environmental Scanning Electron Microscopy equipped with an energy?dispersive X-ray analysis system is employed to examine the chemical compositions?of the nanocomposite fibers. It is found that incorporating the silver nanoparticles
by melt-compounding caused severe aggregation of the nanoparticles at the?polypropylene fiber surface. By contrast, the coverage of the sputter coated fiber?surfaces is much more consistent. The anti-bacterial properties of the nanocomposite
fibers are also investigated and compared. The antibacterial tests revealed the better?performance of silver sputter coated fibers.
