Special Issue Information

Dear Colleagues,

In recent years, the rapid development of the new generation of high-frequency communication technology has driven the development of related electronic equipment and devices to high power and high integration, in addition to being thin and multi-functional. Although this has significantly improved product performance, it has caused serious electromagnetic radiation pollution. High performance electromagnetic interference (EMI) shielding materials are urgently needed to provide high efficiency EMI protection function so as to ensure the normal operation of various types of electronic equipment, information security and human health. The development of polymer-based EMI shielding composites provides an alternative to the traditional metal EMI shielding mode. The EMI shielding efficiency and frequency band of composites can be controlled by means of filler modification and structural design. In addition, excellent machining properties and lightweight advantages of polymer matrix also effectively broaden the frontier applications of EMI shielding composites.

Recognizing the critical role of polymer-based EMI shielding composites in the field of electromagnetic protection materials, this Special Issue of Polymers invites contributions addressing several aspects of polymer-based electromagnetic interference shielding composites, including, though not limited to, the following:

  • structure design of polymer-based EMI shielding composites;
  • mechanism of EMI shielding;
  • calculation and simulation of EMI shielding;
  • multifunctional polymer composites based on EMI shielding;
  • application of polymer-based EMI shielding composites.

The above list is only indicative and by no means exhaustive; any original work or review articles on polymer-based electromagnetic interference shielding composites is welcome.

Three types of composites were tested for electromagnetic interference (EMI) absorption shielding effectiveness, the curing process, and their physical–mechanical properties. For the first type of composites, nickel–zinc ferrite, manganese–zinc ferrite, and both fillers in their mutual combinations were incorporated into acrylonitrile–butadiene rubber. The overall content of the filler, or fillers, was kept at 200 phr. Then, carbon black or carbon fibers were incorporated into each rubber formulation at a constant loading of—25 phr, while the content of magnetic fillers was unchanged, at —200 phr. This work focused on the understanding of correlations between the electromagnetic shielding parameters and electrical conductivity of composites in relation to their EMI absorption shielding effectiveness. The absorption shielding abilities of materials were evaluated within a frequency bandwidth from 1 MHz to 6 GHz. This study revealed good correlation among permittivity, conductivity, and EMI absorption effectiveness. Although the absorption shielding efficiency of composites filled only with ferrites seems to be the highest, the absorption maxima of those composites reached over 6 GHz. The application of carbon-based fillers resulted in the higher electrical conductivity and higher permittivity of composites, which was reflected in their lower absorption shielding performance. However, the composites filled with ferrites and carbon-based fillers absorbed electromagnetic radiation within the desired frequency range. The presence of carbon-based fillers caused improvement in the tensile behavior of composites. This study also demonstrated that the higher the ratio of nickel–zinc ferrite in combined magnetic fillers, the better the absorption shielding efficiency. Full article
