AI Technical Summary
Existing microwave absorbing materials have poor microwave absorption performance, making it difficult to achieve the comprehensive goals of thinness, lightness, wide bandwidth, and strength. Furthermore, wide bandwidth absorption at low filler ratios presents challenges.
Microwave absorbing materials are prepared by constructing a spatially continuous conductive network using conductive fibers, metal oxide nanoparticles, and layered conductive materials, and through specific combinations and interactions.
Achieving high-efficiency absorption over a wide bandwidth at low filler ratios enhances the electromagnetic wave absorption capacity and mechanical properties of materials, reduces electromagnetic pollution, and protects biological health and nearby electronic devices.
