High-frequency electromagnetic waves and electronic products can bring great
convenience to people’s life, but lead to a series of electromagnetic interference
(EMI) problems, such as great potential dangers to the normal operation of electronic
components and human safety. Therefore, the research of EMI shielding
materials has attracted extensive attention by the scholars. Among them,
polymer-based EMI shielding materials with light weight, high specific strength,
and stable properties have become the current mainstream. The construction of
3D conductive networks has proved to be an effective method for the preparation
of polymer-based EMI shielding materialswith excellent shielding effectiveness
(SE). In this paper, the shielding mechanism of polymer-based EMI shielding
materials with 3D conductive networks is briefly introduced, with emphasis
on the preparation methods and latest research progress of polymer-based EMI
shielding materials with different 3D conductive networks. The key scientific
and technical problems to be solved in the field of polymer-based EMI shielding
materials are also put forward. Finally, the development trend and application
prospects of polymer-based EMI shielding materials are prospected.
