Effects of recycled Fe2O3 nanofiller on the structural, thermal, mechanical, dielectric, and magnetic properties of PTFE matrix

The purpose of this study was to improve the dielectric, magnetic, and thermal properties of polytetrafluoroethylene (PTFE) composites using recycled Fe2O3 (rFe2O3) nanofiller. Hematite (Fe2O3) was recycled from mill scale waste and the particle size was reduced to 11.3 nm after 6 h of high-energy b...
