Super‐Wideband Electromagnetic Absorbing TiC/SiOC Ceramic/Glass Composites Derived from Polysiloxane and Titanium Isopropoxide with Low Thickness (<1 mm)

Herein, TiC/SiOC ceramic/glass composites with excellent electromagnetic wave (EMW) absorbing performance are fabricated by pyrolysis of polycarbosiloxane and titanium (IV) isopropoxide (TTIP). By taking advantage the polymer‐derived route, phase compositions microstructures easily tuned. The investigated X‐ray diffraction (XRD) analysis, scanning electron microscope, transmission microscopy/energy dispersive spectroscopy. Nanoscaled TiC is formed uniformly distributed without clustering within SiOC matrix. Thermogravimetric Analysis (TGA) in situ XRD results revealed good thermal stability oxidation resistance mechanism. presented material system (TiC/SiOC) shows a super‐wide microwave absorption bandwidth (EAB) 13.5 GHz, including entire Ka‐band (26.5–40 GHz) low thickness requirement (<1 mm). superior EMW properties ceramics attributed to optimal interface polarization, as well ordering, concentration, interconnectivity conductive network, which all determine electrical conductivity composites.
