| 英文摘要 | The development of functional materials with dual characteristics of microwave absorption and low infrared emissivity is vital for protection against magnetic-wave contamination. Currently, both microwave protection and infrared protection technologies are developing rapidly, but simultaneous integration of both has not been extensively investigated. Herein, a new ternary core-shell CoFe2O4@SiO2@ZAO composite dual-functional material was designed and fabricated. The process consisted of coating CoFe2O4 microspheres with ZAO based on SiO2 middle layer prepared through hydrolysis and sol-gel methods. The introduction of ZAO and SiO2 was found conducive to dielectric loss and impedance matching, thereby improving wave absorption. The nano-flower ZAO coating provided low infrared emissivity with a lamellar structure and high carrier concentration in the resulting ternary structure. The rise in ZAO content first enhanced the wave absorption of CoFe2O4@SiO2@ZAO and then decreased while the infrared emissivity declined. Among prepared samples, CoFe2O4@SiO2@ZAO exhibited a minimum reflection loss (RLmin) of −59.31 dB at 10.96 GHz, conducive to effective absorption bandwidth (EAB) of 4 GHz at 2 mm thickness with an infrared emissivity of 0.71 in 8–14 μm waveband. In sum, the novel CoFe2O4@SiO2@ZAO core-shell structure showed attractive properties in terms of compatibility of wave absorption and infrared emissivity, promising for future syntheses of dual-functional materials with improved performance. © 2023 Elsevier Ltd and Techna Group S.r.l. |
