A Mössbauer study of iron/polytetrafluoroethylene nanocomposites prepared by high-energy ball milling

Abstract Iron/polytetrafluoroethylene (Fe/PTFE) nanocomposites were prepared by means of high-energy ball milling for different lengths of time. Three new components of FeF 2 , FeF 3 , and Fe 3 C in the resultants were mainly investigated using the Mossbauer spectroscopy (MS). The components and average grain size of the nanocomposites were also measured using X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively.
