Thermal conductivity of Aluminum/Graphene metal-matrix composites: From the thermal boundary conductance to thermal regulation

Insights into Interfacial Thermal Resistance in Bi2Te3/Graphene Composites for Thermoelectric Applications

“…The ITR exhibits an approximately 26% increase from 2.16 × 10 –8 m 2 K/W ( N = 1) to 2.73 × 10 –8 m 2 K/W ( N = 5). A similar phenomenon was observed in the heat transport across the metal/graphene interface in metal/graphene composites, , which was attributed to the increased phonon scattering at the interface induced by the increased graphene layer number.…”

“…As defects changed the cross-plane phonon of graphene, leading to stronger cross-plane phonon coupling between graphene and Bi 2 Te 3 , the ITR decreases, or in other words, the interfacial thermal conductance increases. Defects in graphene resulting in increased interfacial thermal conductance was also observed in previous studies of graphene/MoS 2 , 37 graphene/h-BN, 45 and graphene/metal 35,46 interfaces.…”

Unexpected reduction in thermal conductivity observed in graphene/h-BN heterostructures

“…In the field of micro-nano device fabrication, 1 two-dimensional nanomaterials 2 such as graphene 3 and hexagonal boron nitride (h-BN) 4 have been gaining significant attention because of their extraordinary mechanical, [5][6][7][8] electrical, [9][10][11][12] and thermal characteristics. [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Particularly, these materials show broad application prospects when they form vertically stacked van der Waals heterostructures 29 or planar heterostructures. [30][31][32] The graphene/h-BN heterostructure possesses exceptional thermal transport properties, making it a promising candidate for various applications such as thermal rectifiers, 33,34 thermal transistors, 35,36 thermal diode circuits 37 and thermal memory devices.…”

Flexible and thermally conductive epoxy‐dispersed liquid crystal composites filled with functionalized boron nitride nanosheets

“…Thermal conductive polymers are widely used in 5G communication, radar technology, new energy vehicles and flexible wearable electronics by reason of their high flexibility, good electrical insulation performance, lightweight, high strength, chemical resistance, low cost, and easy processability 5–10 . Recent years, a lot of studies have been carried out to improve the polymer materials' TC by either synthesizing intrinsically 11–13 thermal conductive polymers or introducing high TC's fillers 14,15 …”
