“…When combined with functional GO (FGO), the GFs exhibited a better TIMs performance due to the reduced thermal resistance between the GFs and the microelectronic chips by the FGO. Besides thermal management applications, GFs and related films can also be applied in various other applications, such as electromagnetic interference (EMI) shielding, gas barriers, and energy storage and sensors [35,36,88,[93][94][95][96][97][98][99][100], owing to their superior electrochemical and mechanical properties. …”

Thermal management in microelectronic devices has become a crucial issue as the devices are more and more integrated into micro-devices. Recently, free-standing graphene films (GFs) with outstanding thermal conductivity, superb mechanical strength, and low bulk density, have been regarded as promising materials for heat dissipation and for use as thermal interfacial materials in microelectronic devices. Recent studies on free-standing GFs obtained via various approaches are reviewed here. Special attention is paid to their synthesis method, thermal conductivity, and potential applications. In addition, the most important factors that affect the thermal conductivity are outlined and discussed. The scope is to provide a clear overview that researchers can adopt when fabricating GFs with improved thermal conductivity and a large area for industrial applications.

“…using different kinds of nanofillers as discussed elsewhere to increase miscibility and to minimize phase separation [ 7 , 8 ]. The main nanofillers presently used to reinforce the properties of blend nanocomposites are graphene, graphene oxide, and single/few-layer Boron Nitride (BN) [ 9 , 10 ]. The aforementioned nanofillers have their own advantages and disadvantages, but have great impact on new material innovations.…”

The industrial advancement of high-performance technologies directly depends on the thermo-mechanical properties of materials. Here we give an account of a facile approach for the bulk production of a polyethylene terephthalate (PET)/polypropylene (PP)-based nanocomposite blend with Inorganic Fullerene Tungsten Sulfide (IF-WS2) nanofiller using a single extruder. Nanofiller IF-WS2 was produced by the rotary chemical vapor deposition (RCVD) method. Subsequently, IF-WS2 nanoparticles were dispersed in PET and PP in different loadings to access impact and their dispersion behavior in polymer matrices. As-prepared blend nanocomposites were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), dynamic differential scanning (DSC), dynamic mechanical analysis (DMA), and X-ray diffraction (XRD). In this work, the tensile strength of the PP/PET matrix with 1% IF-WS2 increased by 31.8%, and the thermal stability of the sample PP/PET matrix with 2% increased by 18 °C. There was an extraordinary decrease in weight loss at elevated temperature for the nanocomposites in TGA analysis, which confirms the role of IF-WS2 on thermal stability versus plain nanocomposites. In addition, this method can also be used for the large-scale production of such materials used in high-temperature environments.

“…However, the TC value of most polymers usually fall within a low range of 0.1–0.2 W m −1 K −1 due to their low crystallinity . To increase the TC of polymer, the traditional method is to introduce various inorganic fillers with high TC, for example, metal oxides (e.g., Al 2 O 3 and MgO ) and ceramic particles (e.g., AlN and BN ). Generally, the loading of fillers are always high to construct the thermally conductive network through the whole sample, which result in the degradation of the mechanical properties of the polymers .…”

3D Graphene sponge (GS) supported boron nitride (BN) skeleton (BN@GS) was fabricated through a facile method by using ammonium sulfide under mild conditions. Then, BN@GS sponge was infiltrated by epoxy resin to prepare the composites. The microstructures of BN@GS were controlled by adjusting the mass ratio of GS to BN and the dimension of BN to obtain thermally conductive but electrically insulating polymer composites. The thermal and electrical properties of composites were investigated and the results showed that thermal conductivity of composites reached 0.588 W m−1 K−1 at a low GS loading of 0.157 wt%, which was twice as large as the BN/epoxy composites without graphene. When the mass ratio of BN to GS was 60:1 and 100:1, the electrical conductivity of the resin composites corresponded to insulator region. The 3D continuous network of GS endowed the composites with enhanced thermal conductivity at a relatively low filler loading. In addition, the introduction of BN cut off the transmission of electrons which resulted in the composites with electrical insulation. The hybrid fillers were introduced to guarantee the enhanced thermal conductivity and electrical insulation at a relatively low filler loading. The thermal conductivity of the BN@GS/epoxy composites coincide well with the surface temperature variation of the BN@GS/epoxy composites acquired from an infrared camera. The mechanical properties of BN@GS/epoxy composites improved remarkably in comparison with pure epoxy resin. POLYM. COMPOS., 40:E1600–E1611, 2019. © 2019 Society of Plastics Engineers
