Acquirement of Strong Microwave Absorption of ZnFe₂O₄@SiO₂@Reduced Graphene Oxide/PVDF Composite Membranes by Regulating Crystallization Behavior

Currently, the microwave absorption materials with high absorbing efficiency are in urgent need to reduce electromagnetic pollution. Herein, the ZnFe2O4@SiO2 core–shell microspheres were synthesized and combined with reduced graphene oxide (RGO) to form the ingenious hierarchical composites (ZnFe2O4@SiO2@RGO), which were used as wave absorbing functional nanofillers of semicrystalline polyvinylidene fluoride (PVDF) matrix. The microstructure and...
