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.

“…Traditional fillers include carbon black, 15,16 zinc oxide fillers, 17,18 boron nitride fillers, 19 diamond fillers, 20 and others. [21][22][23][24][25][26][27][28] However, to improve the thermal conductivity of a polymer such as silicon rubber, these traditional fillers must have a large enough weight (wt) load, which greatly affects their physical properties, 29 especially their elastic properties. Compared with these traditional particles, aluminum nitride (ALN) has a higher thermal conductivity, 30 and at the same volume fraction, the ALN filler can make the SR with good physical properties.…”

This study presents aluminum nitride/silicone rubber composite as a drag reduction material, inspired by the boundary heating drag reduction mechanism of dolphin skin. Aluminum nitride was added as a thermal conductive filler at weight fractions of 16.67, 21.05, and 28.57 wt% to pristine silicone rubber. Tests of the thermal conductivity and tensile properties showed that the thermal conductivity of all three aluminum nitride/silicone rubber composites were increased 27.9%, 41.4%, and 43.7% than that of the pristine silicone rubber, and the elastic modulus of the composites was increased with the aluminum nitride content. Droplet velocity testing, which can reflect the drag reduction mechanism of the heating boundary controlled by the aluminum nitride/silicone rubber composites, was performed between all three aluminum nitride/silicone rubber composites and pristine silicone rubber. The results showed that the droplet velocity of all three aluminum nitride/silicone rubber composites were higher than pristine silicone rubber, implying that the composites had a drag-reducing function. In terms of the drag-reducing mechanism, the heat conductivity performance of the aluminum nitride/silicone rubber accelerates the heat transfer between the aluminum nitride/silicone rubber composite surface and droplet. The forces between the molecules and droplet dynamic viscosity are reduced, which result in drag reduction. The application of aluminum nitride/silicone rubber composite to control fluid medium will have important value for fluid machinery.

The reinforcement of polymer matrices with continuous carbon fibers (CF), giving rise to so-called carbon fiber-reinforced polymers/plastics (CFRP) composites is a major issue in the space, aerospace, naval, wind and oil and gas energy industries because of their need for construction materials that exhibit very high structural efficiency (i.e., exceptional strength/ density and stiffness/density ratios). The improvement in interfacial strength between the polymer matrix and reinforcing fiber system leading to the enhancement of overall mechanical performance of CFRPs has always been sought by materials scientists, since the region separating the bulk polymer from the fiber reinforcement is of utmost importance to load transference and distribution. Kim and Mai [1] and Pegoretti et al. [2] discovered that the shear strength of a fibrous polymer composite is closely related to the shear strength of the fibersurrounding polymer matrix domain. They also noted that the latter property strongly depends upon the mechanical performance of the interphase, which constitutes an intermediate, different phase when compared to the reinforcing fiber and the bulk resin [3]. Many efforts were then devoted to build strong fiber/ matrix interphases by controlling physicochemical interactions and frictional forces acting on this particular region of composite systems [4]. That achievement [1, 2] allowed efficient hierarchical composite structures to be technologically addressed and developed, aiming not only to improve the mechanical strength but also to mitigate interlaminar, intralaminar and translaminar damage, hence enhancing the fracture toughness as well [5][6][7]. For instance, the use of fillers such as monolayer graphene [8][9][10] Abstract. In this paper, a cost-effective and eco-friendly method to improve mechanical performance in continuous carbon fiber-reinforced polymer (CFRP) matrix composites is presented. Unsized fiber fabric preforms are coated with self-assembling sugarcane bagasse microfibrillated cellulose, and undergo vacuum-assisted liquid epoxy resin infusion to produce solid laminates after curing at ambient temperature. Quasi-static tensile, flexural and short beam testing at room temperature indicated that the stiffness, ultimate strength and toughness at ultimate load of the brand-new two-level hierarchical composite are substantially higher than in baseline, unsized fiber-reinforced epoxy laminate. Atomic force microscopy for height and phase imaging, along with scanning electron microscopy for the fracture surface survey, revealed a 400 nm-thick fiber/matrix interphase wherein microfibrillated cellulose exerts strengthening and toughening roles in the hybrid laminate. Market expansion of this class of continuous fiber-reinforced-polymer matrix composites exhibiting remarkable mechanical performance/cost ratios is thus conceivable.
