Abstract

Fe3O4 multi-granule nanocluster–multiwall carbon nanotube composites for microwave absorbing applications are fabricated by the surface-engineered tape-casting method. The multi-granule nanoclusters are synthesized by a modified polyol hydrothermal method and characterized by transmission electron microscopy, X-ray diffraction and vibrating sample magnetometer. The complex permittivity and permeability of the composites with different granule size of nanoclusters are characterized in X-band range with the reflection method. The absorption peak of the composites are shifted from 11.1[Formula: see text]GHz to 11.51[Formula: see text]GHz as granule size increased from 18[Formula: see text]nm to 35[Formula: see text]nm.
