synthesis and characterization of hematite Fe2O3 nanofiller for enhanced dielectric and microwave-absorbing properties in PTFE composites

This paper presents the synthesis of hematite Fe2O3 nanofiller from mill scales and its application in polytetrafluoroethylene (PTFE) composites for enhanced dielectric and microwave-absorbing properties. The nanofiller was obtained through 9 hours of high-energy ball milling, resulting in a particl...
