Research progress in the preparation of electromagnetic wave absorbing and corrosion resistant nanofiber materials by electrospinning.

[Display omitted] With the development of information technology, electromagnetic interference (EMI) has become a problem that people have to face. Electromagnetic wave absorbing (EMWA) materials is the key to solve this problem. In recent years, one-dimensional (1D) nanofiber EMWA materials have become a research hotspot because of their characteristics that can enhance the loss of electromagnetic waves (EMW). Electrospinning is a simple and effective method to prepare 1D fiber materials, which has the advantages of short preparation period and continuous collection, and has been paid more and more attention. When EMWA materials are used in complex, extreme environments (oceans, acid rain, etc.), they can cause extensive corrosion, resulting in a decrease in absorbing performance. Therefore, it is necessary to design multi-functional EMWA materials such as corrosion resistance. In this paper, the research progress on EMW absorption and corrosion resistance of 1D nanofibers prepared by electrospinning technology in recent years are reviewed. The effect of different fillers on EMW absorption and the effect of different post-treatment methods on the multifunction of the EMWA materials are analyzed. Finally, the advantages and disadvantages of composite EMWA materials prepared by electrospinning technology in different environments are summarized, and suggestions and prospects are put forward.
