Heat dissipation efficiency and electromagnetic interference (EMI) shielding performance are vital to integration, miniaturization, and application of electronic devices. Flexible and designable polymer-based composites are promising candidates but suffer from unavoidable interfacial thermal resistances, anisotropic thermal conductivity, and low shielding of EMI limiting application. Herein, multifunctional epoxy resin (EP)-based composites with an interconnected carbon fibers (CFs) network structure containing a low thermal resistance interfacial were prepared by high-temperature calcination and infiltration. The coherent heat and electron transfer pathways constructed with self-oriented CFs cloth connected by carbon nanotubes (CNTs) converted from leaf-shaped zeolitic imidazolate frameworks (ZIF-L) and stable magnetic property provided by cobalt nanoparticles contained in the CNTs made composites to an integrated in-plane thermal conductivity of up to 7.50 W m −1 K −1 , a through-plane thermal conductivity of 1.96 W m −1 K −1, and an EMI shielding effectiveness of 38.4 dB. Furthermore, the mechanical properties of CFs and the junction effect of CNTs endowed the composites with stability of mechanical property, thermal conductivity, and EMI shielding effectiveness after multiple bendings. The finite element simulation further verified the advantage of CFs network linked by CNTs on heat transfer. This work provides the desired design for the construction of a multifunctional polymer-based composite used in advanced electronic equipment.

The multi-functionalization of polymer composites refers to the ability to connect multiple properties through simple structural design and simultaneously achieve multi-performance optimization. The large-scale design and mass production to realize the reasonable structure design of multifunctional polymer composites are urgently remaining challenges. Herein, the multifunctional MXene/graphene/polymer composites with three-dimensional thermally and electrically conductive network structures are fabricated via the utilization of the microstructure of the soft template, and a facile dispersion dip-coating approach. As a result, the polymer composites have a multi-performance improvement. At the MXene and graphene content of 18.7 wt%, the superior through-plane thermal conductivity of polymer composite is 2.44 W m−1 K−1, which is 1118% higher than that of the polymer matrix. The electromagnetic interference (EMI) shielding effectiveness of the sample reaches 43.3 dB in the range of X-band. And the mechanical property of the sample has advanced 4 times compared with the polymer matrix. The excellent EMI shielding and thermal management performance, along with the effortless and easy-to-scalable producing techniques, imply promising perspectives of the polymer composites in the next-generation smart electronic devices.

With the rapid development of electronic devices toward the miniaturization, integration, and multi‐functionalization, the device stability, reliability, and service life face significant challenges due to the greatly increased heat accumulation. Therefore, it is highly desired to develop efficient thermal dissipation materials in thermal management. Thermally conductive polymer composites are expected to be widely applied in 5G communication, electronic packaging, and energy storage, owing to the ease of processing, good flexibility, low cost, etc. Boron nitride nanosheet (BNNS) is generally used as highly thermal conductive nanofillers for greatly improving the thermal conductivity of polymer. Mass production of high quality BNNS with desired properties and the structural design principles and fabrication methods for polymer/BNNS nanocomposites are critical to achieve extensive applications. Here, this review summarizes the latest advancement of the preparation method of BNNS and its polymer nanocomposites, as well as the innovatively structural design for observably improving the thermal management capability and energy storage performance of polymer/BNNS nanocomposites, expecting to offer some guidance on how to massively fabricate the BNNS and highly thermally conductive polymer composites.
