摘要：

Sr4Fe6O13 ferrites as a new kind of high frequency microwave absorption materials were synthesized by solid-state method, and its high frequency microwave absorption performances were investigated. The carbon nanotubes (CNTs) were added into Sr4Fe6O13 ferrites to form Sr4Fe6O13/CNTs composites with network structure, which improved the high-frequency dielectric performance and microwave absorption capacity. When the mass ratio of Sr4Fe6O13 and CNTs was 20, the Sr4Fe6O13/CNTs composites achieved the strongest absorption capacity (- 51 dB) at frequency of 15 GHz with 1.2 mm thickness. Those results indicate that Sr4Fe6O13/CNTs composites are suitable potential application to high-frequency communication device in suppressing electromagnetic interference.
