| Abstract: | Fe/PTFE nanometer composite was prepared by high energy ball milling,the micrograph and structure was investigated by high resolution TEM andKG-2] 57 Fe Mssbauer spectroscopy.The micrograph of the high resolution TEM shows that the nanometer composite consists of small crystallites with diameter about 8nm separated by grain boundaries of amorphous phase.And the Mssbauer effect studies show that the spectrum can be fitted to three components,one doublet for Fe 2+ ,and two sextets for bulk and interfacial α Fe. |
