Designing high-performance electromagnetic wave absorption materials based on polymeric graphene-based dielectric composites: From fabrication technology to periodic pattern design

Abstract

Since the development of advanced electromagnetic absorption material is highly critical in telecommunication and stealth technology, both fabrication technology and structure design are significant in the achievement of broadband and strong absorption performance. For understanding the effects of fabrication technology and structure design on performance, in this work, two various fabrication methods, including traditional mixing method and novel framework method, are demonstrated to investigate the dispersion capability of reduced graphene oxide in the polymeric matrices. Moreover, artificial structure designs, including layers of unit cell, top-layer shape and top-layer materials, are used for further optimizing the microwave absorption performance. Performance comparison suggests that the fabrication via framework technology is more favorable in obtaining ideal impedance match in the composites. Additionally, the meta-structural design coupled with related mechanism for substantially broadening the absorption bandwidth has been systematically discussed. Implication of the results implies that combination of fabrication technology and periodic pattern design provides a promising platform for achieving high-performance absorption materials.
