Abstract: In order to obtain excellent microwave absorbing materials. BaFe12O19 powders were first prepared by microwave hydrothermal method in this study, and BaFe12O19@SiO2 core–shell structure composite powders with different contents of TEOS were prepared by the improved Stöber method. The morphology and magnetic properties were investigated. PVDF was used as film forming agent, flexible film was prepared by tape casting. The performance was shown that the BaFe12O19@SiO2 microwave absorbing film has a good absorbing performance in the 8–18 GHz band. When the matching thickness is 2.5 mm, the RLmin is −30.3 dB at 15.2 GHz, and the effective bandwidth is 3.4 GHz (14.6–18 GHz). It provides a development direction for future research on flexible absorbing materials.
