| 摘要:随着信息技术的不断发展，电磁干扰（EMI）等问题日益严重，需要构建更先进的电磁干扰屏蔽材料。天然木材本身有着多孔的结构，碳化后保留为三维（3D）骨架，构成巨大导电网络，可作为电磁干扰屏蔽的理想材料。将木基多孔材料与磁性材料、导电材料复合，优化材料的结构与性能，为屏蔽材料的优化提供了思路。本文介绍了天然木材的复合方法，着重综述了木材作为电磁屏蔽材料的最新研究进展，并对其发展前景进行了展望。 |
| Abstract:With the continuous development of information technology， electromagnetic interference （EMI） problems are becoming increasingly serious， and more advanced electromagnetic interference shielding materials need to be constructed. Natural wood has a porous structure， and can be retained as a three-dimensional （3D） skeleton after carbonization， forming a huge conductive network， which can be used as an ideal material for electromagnetic interference shielding. Wood-based porous materials can also be compounded with magnetic materials and conductive materials to optimize the structure and performance of the materials， providing ideas for the optimization of shielding materials. The composite methods of natural wood， especially the latest research progress of wood as electromagnetic shielding materials were introduced in this paper， and the development prospects were looked forward. |
