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.
