Thermal interface materials with sufficiently vertically aligned and interconnected nickel-coated carbon fibers under high filling loads made via preset-magnetic-field method

Ultrahigh thermal conductive polymer composites by the 3D printing induced vertical alignment of carbon fiber

“…† The lowest thermal conductivity is of the composite materials with random structures prepared by casting, 12,46,47 and their thermal conductivity is lower than 10 W m −1 K −1 . Due to the weak driving force, the composite prepared by approaches of ice template, 28,48,49 magnetic eld, 11,50,51 and electric eld 23,52,53 is not enough to align the high content of ller, so it only obtains slightly higher thermal conductivity. In contrast, satisfactory values were obtained for composites with strong mechanical stress induced 18,22,54 orientation.…”

Functional PDMS Elastomers: Bulk Composites, Surface Engineering, and Precision Fabrication

“…PDMS-based composites are promising candidates for thermal interface materials due to the high mechanical flexibility, electrical insulation, and chemical inertness of PDMS. [67] However, the intrinsically low thermal conductivity of PDMS (≈0.15 W m −1 K −1 ) [68] may prevent its use in high-performance applications. To overcome this limitation, thermally conductive fillers are required.…”

Multi-scale hybrid spherical graphite composites: a light weight thermal interface material with high thermal conductivity and simple processing technology

“…Furthermore, brous llers are characteristic high aspect ratios llers. In order to attain excellent thermal conductivities, the ller is necessary to realize orientational arrangement in polymer matrix, 24,25 which makes the processing technology of TIMs more complicated. For spherical llers, although it has no advantage in low lling content, it can form more thermal conductive chains through high lling content, thus realizing fast heat transfer and dissipation.…”
