Electromagnetic interference problems have become an increasing issue with the rapid development of wireless information technologies,which has attracted global attention.The key solution to this challenge is to develop materials that can absorb electromagnetic waves.The ideal absorbing material should be a structural material integrating load bearing,heat protection and strong absorption.The carbon-based,ceramic-based composites and their electromagnetic absorption properties in recent years were summarized in this review.The ultimate goal of these absorbers is to achieve broader effective absorption frequency bandwidth at a thin coating thickness.The synthesis methods,structures and electromagnetic wave loss mechanism of several typical and well-received composites were introduced.The superiorities,research status and main problems of absorbing materials were described.Based on these progresses,the potential development direction of absorbing materials in the future was predicted. |
