“…In addition to ensuring its excellent EMI shielding performance, it also needs to have good flexibility, thermal conductivity, self-heating performance and mechanical properties [ 34 , 35 ]. By introducing multifunctional fillers and constructing the layered structure, it is feasible to realize the multifunctional compatibility design of polymer-based EMI shielding composites [ 36 , 37 ].…”

The rapid development of aerospace weapons and equipment, wireless base stations and 5G communication technologies has put forward newer and higher requirements for the comprehensive performances of polymer-based electromagnetic interference (EMI) shielding composites. However, most of currently prepared polymer-based EMI shielding composites are still difficult to combine high performance and multi-functionality. In response to this, based on the research works of relevant researchers as well as our research group, three possible directions to break through the above bottlenecks are proposed, including construction of efficient conductive networks, optimization of multi-interfaces for lightweight and multifunction compatibility design. The future development trends in three directions are prospected, and it is hoped to provide certain theoretical basis and technical guidance for the preparation, research and development of polymer-based EMI shielding composites.

“…As a typical polymer materials, silicone rubber possesses excellent electrical insulation, high and low temperature resistance and easy process ability, and has been used in fabrication of electronic systems [4]. However, the low thermal conductivity and poor damping properties of pure silicone rubber cannot satisfy some stringent requirements [5]. Recently, carbon materials such as carbon nanotube [6], graphene [7], and graphite [8] have been widely used to improve the thermal conductivity and damping properties of polymers.…”

High integration and miniaturization of electronic systems require thermal conductivity and mechanical damping materials. In this work, hexagonal boron nitride (hBN) particles were modified by vinyltrimethoxysilane (V171) and hexadecyltrimethoxysilane (N3116) for comparing, and described as V171-hBN and N3116-hBN, respectively. The pristine and surface modified hBN were filled in vinylmethylpolysiloxane (VMQ), and then vulcanized to fabricate hBN/silicone rubber composites. The damping properties of V171-hBN/silicone rubber composites were considerably higher than that of pristine hBN/silicone rubber composites, while for N3116-hBN/silicone rubber composites were in contrast. The strong interfacial action in V171-hBN/silicone rubber composites came from the chemical bond by vinyl groups on the surface of V171-hBN taking part in the vulcanization of VMQ. This strong interfacial action led the deformation of hBN, and the internal friction between layers of hBN significantly increased to dissipate more energy. As a result, V171-hBN/silicone rubber composites with excellent damping and thermal conductivity as well as good mechanical properties were obtained.

With the rapid development in the aerospace field, there is an increasing demand for flexible ablation materials with excellent cyclic ablation property, which attracts more and more attention from researchers all over the world. In this paper, the uniform experimental design method is used to prepare lamellar material filled epoxy modified vinyl silicone rubber (EMVSR) flexible ablation resistant composite materials. The effects of three layered materials (lamella sericite, MoS2, and GO) on the ablation performance and thermal insulation performance of EMVSR materials under cyclic ablation conditions are discussed. In addition, the compressive strength of the composites after ablation and the density of the char layer are tested and analyzed. The test results show that all these sheet materials can enhance the heat resistance and thermal conductivity of the EMVSR composites and GO has the greatest impact. The back‐face temperature of the EMVSR composites after the second ablation is higher than that after the first ablation, and GO can significantly improve the material's heat insulation performance under cyclic ablation conditions. The mass ablation rate of the EMVSR composites after the second ablation is generally greater than that after the first ablation. GO and sericite will reduce the ablation resistance of the materials, while MoS2 will increase the ablation resistance of EMVSR composites. The compressive strength of the char layer and the ablative resistance of the materials are positively correlated with the density of char layer.
