Abstract
- Superior electromagnetic (EM) wave absorption properties in 8.2–12.4 GHz (X-band) can be obtained via the effective combination of polyaniline (PANI) and SnO 2 nanoparticle cluster. In this work, SnO 2 nanoparticle cluster@PANI (SnO 2 @PANI) core-shell microspheres were firstly fabricated via a hydrothermal process followed by in-situ polymerization, and the EM wave absorption properties of SnO 2 @PANI core-shell microspheres in X band were studied. The related structure and morphology analyses indicated SnO 2 @PANI core-shell microspheres were successfully synthesized with PANI coated on the surface of SnO 2 nanoparticle cluster. The minimum reflection loss (RL min) of − 69.1 dB (thickness of 2.78 mm) and effective absorption bandwidth (EAB) covering the whole X-band (when the thickness was from 2.5 to 3.1 mm) was achieved. Remarkable EM wave absorption properties of SnO 2 @PANI core-shell microspheres were mainly attributed to the outstanding impedance matching characteristic and dielectric loss capability (conduction loss, interfacial polarization loss and dipole polarization loss). • SnO 2 @PANI core-shell micropheres have been synthesized via a hydrothermal process followed by in-situ polymerization. • The excellent reflection loss of SnO 2 @PANI core-shell micropheres is − 69.1 dB with a matching thickness of 2.78 mm. • The effective absorption bandwidth of SnO 2 @PANI core-shell micropheres could cover the whole X-band.
