Dielectric and microwave absorption performances of hollow C/TiO2 composite microspheres

Dielectric and microwave absorption performances of hollow C/TiO2 composite microspheres

Hollow TiO 2 microspheres and carbon/TiO 2 (HC/T) composite microspheres have been synthesized by a one-pot synthesis approach. The complex permittivity result shows that the hollow TiO 2 /paraffin composites have weak polarized loss, and the permittivities of the hollow HC/T/paraffin composites can...

Zusammenfassung:Hollow TiO 2 microspheres and carbon/TiO 2 (HC/T) composite microspheres have been synthesized by a one-pot synthesis approach. The complex permittivity result shows that the hollow TiO 2 /paraffin composites have weak polarized loss, and the permittivities of the hollow HC/T/paraffin composites can be easily tuned by the carbonization temperature. The result of reflection loss ( RL ) exhibits that the microwave absorption performances of HC/T composite are more excellent than hollow TiO 2 . The hollow HC/T composite carbonized at 800°C shows the most excellent microwave absorption performances because of suitable complex permittivity and impedance matching. Graphic abstract
