Carbon materials for structural self-sensing, electromagnetic shielding and thermal interfacing

An asymmetric electrically conducting self-aligned graphene/polymer composite thin film for efficient electromagnetic interference shielding

“…[9][10][11][12][13][14][15][16][17][18] However, there is still lack of flexible and light weight shielding materials, which is required for current electronics/devices. Graphene-based composite materials have been attracted a significant research interest due to their remarkable properties including low density, high surface area, large aspect ratios, versatile processing, ultrahigh electrical conductivity and excellent mechanical stiffness.…”

Solder–Graphite Network Composite Sheets as High-Performance Thermal Interface Materials

“…The comparison involves a large variety of TIMs, due to the extensive prior work of one of the authors (D.D.L.C.). [1][2][3][4][5][6][7]10,11,20,21 EXPERIMENTAL PROCEDURES…”

“…A very high value of the thermal conductivity [67 W/(m K)] has been reported for tin nanowires, but the thermal contact conductance for tin nanowires [5.0 9 10 4 W/(m 2 K)] is less than that [12][13][14][15][16][17][18][19][20][55][56][57] and nanofibers 58 have received much recent attention in relation to their potential as TIMs. A thermal contact conductance of 1.6 9 10 4 W/(m 2 K) has been reported for a carbon nanotube adhesive grease.…”

“…Yet another example is a carbon nanotube array, with the direction of the nanotubes being perpendicular to the plane of the sheet. [12][13][14][15][16][17][18][19][20] However, carbon nanotube arrays suffer from high material cost and processing complexity, which stems from the fact that the nanotubes need to grow from a suitable substrate at a sufficiently high temperature. Due to the large thickness of a thermal interface sheet (e.g., 7 lm to 510 lm 11 ) compared with a layer of thermal paste (e.g., 0.2 lm to 7 lm 21 ), high thermal conductivity in the through-thickness direction of the sheet is more important for a thermal interface sheet than a thermal paste.…”

Barium ferrite decorated reduced graphene oxide nanocomposite for effective electromagnetic interference shielding

“…5 On the other hand, carbon based composites have gained significant popularity as EMI shielding materials because of their low cost, facile synthesis and ease of processing. 1,[6][7][8][9][10] Graphene, a flat monolayer of carbon atoms tightly packed into a two dimensional honeycomb lattice, has acquired tremendous consideration owing to its unique properties such as remarkable structural flexibility, superior electrical conductivity, thermal stability and extraordinary mechanical properties. 11 Due to its superior in-plane properties, graphene and graphene-like nanomaterials are promising candidates for many potential applications in many technological fields such as polymer nanocomposites, 12 supercapacitors, 13,14 nanoelectronics, 15 energy storage devices, 16 batteries, 17 and sensors.…”
