摘要:

隨著現代電子信息技術的飛速發展，電磁波輻射和污染嚴重干擾精密電子元器件的正常工作，并直接危害信息安全和人體健康。聚合物基電磁屏蔽材料能有效防止電磁波輻射和污染，當前使用環境對其提出了低反射、高吸收、寬頻帶和結構/功能一體化的苛刻要求，發展多元復合結構是解決這些難題的有效手段。基于材料對電磁波的屏蔽機理，重點介紹了聚合物基電磁屏蔽材料的多孔復合結構、異質復合結構、多層復合結構、梯度復合結構和超結構，以及這幾類多元復合結構的設計、制備技術及其電磁損耗機制的最新研究進展，并展望了其未來發展方向。該綜述可為厚度薄、密度小、頻帶寬、吸收強的新型寬頻電磁屏蔽復合材料的結構設計和制備方法研究提供借鑒。

Abstract:

With the rapid development of modern electronic information technology, electromagnetic radiation and pollution seriously disturb the normal work of precision electronic components, and directly endanger information security and human health. Polymer-based electromagnetic shielding materials can effectively prevent electromagnetic radiation and pollution, but the current usage environment puts forward strict requirements for low reflection, high absorption, broadband and structure/function integration. The development of multi-element composite structure is an effective way to solve these problems. Based on the shielding mechanism of materials to electromagnetic waves, the porous composite structure, heterogeneous composite structure, multi-layer composite structure, gradient composite structure and meta�瞫tructure of polymer-based electromagnetic shielding materials, as well as the latest research progress of design, preparation technology and electromagnetic loss mechanism of these types of multi-component composite structures, were mainly introduced. Moreover, the future development of multi-element composite structures was prospected. This review may provide suggestions for the structural design and preparation of novel broadband electromagnetic shielding composites with thin thickness, light density, wide effective band and strong absorption.
