Abstract
ABSTRACTFeNi nanopowders are dispersed into the polypropylene to form FeNip/PP nanocomposites by a combination method of high-temperature solution blending process and two-step blending process. The excellent dispersion of FeNi nanoparticles led to significant improvements in mechanical and soft magnetic properties. When the powders content is in the range of 1 ∼ 3 wt.%, the strength of PP resin reached its peak strength which is 20 ∼ 27% higher than that of the pure resin. The composites have wave-absorbing properties in the frequency range of 1 ∼ 2 GHz. It was concluded that the multi-step dispersion process is a simple and versatile way for the fabrication of polyolefin-based nanocomposites with superior functionalities.
