Abstract

The multi-layer TiO₂ aerogel-coated polymer scaffold (PS) composite containing 5 wt% of Fe₃O₄ nanoparticles was synthesized via the chemical liquid deposition of multiple layers of TiO₂ aerogel onto the macroporous PS. The combination of the toughness, magnetic, and lightweight nature of the PS and the excellent microwave absorption properties of TiO₂ specify that the composite could be used as a novel microwave absorbing material. The surface morphological results indicate that the pores of PS were mostly filled and covered by the TiO₂ aerogel. The PS was used to reduce the weight of the microwave absorber, while the porous TiO₂ aerogel and Fe₃O₄ particles were introduced to provide enhancement in the microwave absorption properties of the composite. Although the pristine PS showed 40% microwave absorption in the X-band region, the 10-times dip-coated TiO₂ aerogel-PS composite enhanced the microwave absorption up to 70%, and this value reached 80% for the 15-times dip-coated sample.
