Improving through-plane thermal conductivity of PDMS-based composites using highly oriented carbon fibers bridged by Al2O3 particles

GMP/Al2O3/ZnO/PDMS thermal interface materials with anisotropic thermal conductivity and electrical insulation ability obtained by 3D‐printing method

“…In such processes, anisotropic fillers tend to align perpendicular to the flow direction when transferred from a wide channel to a narrow channel. 26 Based on this principle, 3D printing has emerged as an innovative technology for fabricating materials with anisotropic structures. 27,28 This technology offers notable advantages such as excellent design flexibility, scalability, and cost-effectiveness, making it well-suited to produce anisotropic structural materials.…”

“…Shear‐induced orientation is a simple and convenient method of achieving alignment, commonly observed in various extrusion processes. In such processes, anisotropic fillers tend to align perpendicular to the flow direction when transferred from a wide channel to a narrow channel 26 . Based on this principle, 3D printing has emerged as an innovative technology for fabricating materials with anisotropic structures 27,28 .…”

Flexible, High Thermal Conductivity, and EMI Shielding Performance Thermoplastic Polyurethane Composites through Reinforced-Orientation Carbon Fiber

“…Besides, in practical applications, heat dissipation often occurs along a specific direction, such as the requirement for good in-plane TC materials to remove the heat generated by the hot spots. There are various strategies available for regulating the orientation of CF, such as electrostatic flocking, external electric or magnet field assisted-alignment, flow shearing force induced-orientation, , directional freeze-drying, or a 3D printing method . Although the above composites exhibit good thermal conductivity, their EMI shielding performance has been rarely reported, possibly due to the vertically oriented carbon fibers, which may result in the inability to simultaneously achieve both satisfactory TC and good EMI shielding performance.…”

Enhancing Thermal Conductivity, Electrical Insulation, and Mechanical Strength of Polydimethylsiloxane Composites with Sandwich Structure

“…For using the matrix, polydimethylsiloxane (PDMS) is often used as the matrix of TMMs due to its advantages such as low cost, corrosion resistance, and lightweight. [10][11][12] In addition, compared to other polymer materials such as polypropylene, polyvinyl chloride, and other polymers, PDMS has excellent high-temperature resistance and can maintain its physical properties at extreme temperatures. Due to its good biocompatibility, PDMS can also be applied in biological fields such as medical devices and so on.…”
