“…As presented in Figure , the phonon transmission channel of EP/CMWCNT thermosets mainly relied on the CMWCNT network structures. However, the poor dispersion performance of CMWCNTs in EP/CMWCNT composites was still a major factor limiting the TC ability of substantial enhancement . The EP/CNF/CMWCNT composites were successfully obtained by the good dispersion of a small amount of CMWCNTs in 3D cellulose aerogel due to an abundance of both hydroxyl and carboxyl functional groups on the CNF and CMWCNT surface.…”

“…However, the poor dispersion performance of CMWCNTs in EP/CMWCNT composites was still a major factor limiting the TC ability of substantial enhancement. 8 The EP/CNF/CMWCNT composites were successfully obtained by the good dispersion of a small amount of CMWCNTs in 3D cellulose aerogel due to an abundance of both hydroxyl and carboxyl functional groups on the CNF and CMWCNT surface. With 0.65 wt % CMWCNT loading, the TC of EP/CNF/CMWCNT composites was higher than that of EP/CMWCNT composites, which was mainly due to the fact that sufficient and continuous phonon transmission paths could be formed inside the structure of EP/CNF/CMWCNTs.…”

“…With the rapid development of high-power electronic devices and electrical equipment, heat sinking has become a crucial concern and restrained the miniaturization and high integration of electronic products. Therefore, it is urgent to seek high-performance thermal management materials. − Over the past decade, epoxy resin (EP) composites were widely used as substrates and packing materials in the field of electronic packing and devices due to their unique chemical stability, excellent electrical insulation, and good design freedom. , However, the pristine EP possesses a relatively low thermal conductivity (TC, 0.2 W·m –1 ·k –1 ), which is far from satisfying the cooling requirements of contemporary electronic devices for high integration, miniaturization, and multifunction. − Recently, a wide variety of thermal conductive fillers have been used to enhance the TC of EP composites, such as carbon nanotubes (CNTs), graphene nanosheets, boron nitride (BN), aluminum nitride, and carbon nitride . Nevertheless, addition of a large amount of thermal fillers is required to achieve a satisfied TC of composites, but the mechanical properties of thermosets will be deteriorated.…”

High effective thermal management materials have become a crucial factor for the reliability and lifetime of devices. Herein, epoxy resin (EP) composites with superior thermal conductive efficiency were fabricated via the homogeneous dispersion of carboxylated multiwalled carbon nanotubes (CMWCNTs) in cellulose nanofiber (CNF) aerogels, and then the EP precursors were impregnated and cured. The thermal conductivity of EP/ CNF/CMWCNT thermosets containing only 0.65 wt % CMWCNTs increased from 0.19 W•m −1 •k −1 for pristine EP to 0.93 W•m −1 •k −1 and increased by 389.5%. As a result, the composites presented excellent heat absorption and dissipation performance, which are demonstrated by the infrared thermal camera tests. Besides, the composites showed highly electric insulating performance, and its volume electrical resistivity was as high as 6.48 × 10 15 Ω•cm −1 due to the low content of CMWCNTs in thermosets. The glass-transition temperature of EP/ CNF/CMWCNT composites increased from 132.6 °C for neat EP thermosets to 153.3 °C, as indicated by the dynamic mechanical analysis. Moreover, thermal mechanical analysis demonstrated that the resultant EP composites possessed excellent dimensional stability. The obtained EP/CNF/CMWCNT composites were allowed to work at a higher temperature environment. This presented research work provided an alternative approach for preparing EP composites with highly efficient thermal management and electrical insulation performance, which allowed their application in electronic packaging, devices, and other electronic applications.

Polymers are known as thermally insulated materials with reported effective thermal conductivity (K eff ) in the range of 0.1 to 0.5 Wm À1 K À1 . However, increasing demand for smaller and more powerful electronics has created the need for thermally conductive polymers for use in heat exchangers and electronic packaging applications. Given this background, much research has been done over the past two decades to increase the K eff of polymers. Based on the strategy involved, those works can be divided into two main categories:(i) increasing the K eff of the neat polymer by aligning its chains orientation; and (ii) increasing polymer K eff by fabrication of polymeric composites with thermally conductive filler networks. Among these two strategies, the former is limited to nanoscale laboratory research and is difficult to scale up for mass production. Therefore, this work is mainly focused on the latter category, thermally conductive polymeric composites, which has a higher potential for large-scale production. This work aims to summarize, evaluate, and highlight the successful strategies of the recent efforts in enhancing the thermal conductivity of polymer composites. The major achievements, future challenges, and the outlooks of high thermally conductive polymeric composites are presented by analyzing the results of about 300 works.
