Carbon-based Nanomaterials (CNTs, Graphene):

Properties:

Both carbon nanotubes (CNTs) and graphene possess extremely high intrinsic thermal conductivity and excellent mechanical strength. CNTs, due to their one-dimensional structure, are ideal for vertical heat transfer; while two-dimensional graphene excels at in-plane lateral heat diffusion.

1. Superior Electrical Conductivity: Extremely low resistivity allows for rapid electron mobility, offering potential for future applications in smaller, faster next-generation semiconductors and supercapacitors.

2. Excellent Thermal Conductivity: Exceptionally high thermal conductivity enables rapid heat transfer and dissipation, making it suitable for smartphone heat spreaders and high-performance batteries.

Electronic Devices: Used as conductive coatings for components such as circuit boards, touch screens, and sensors to enhance device performance and stability.

Energy Sector: Serves as electrode material or current collector coating in energy storage devices like lithium-ion batteries and supercapacitors, improving energy density and charge-discharge efficiency.

Electromagnetic Shielding: Used to produce electromagnetic shielding materials that effectively block electromagnetic interference, protecting electronic devices from external electromagnetic environments.

Anti-static: Applied as an anti-static coating in scenarios requiring static protection, such as for electronic product protection and PCB anti-static applications.

Applications:

Nano-composite TIMs: Adding CNTs or graphene as fillers to traditional TIM matrices can significantly improve their thermal conductivity.

CNT-based TSVs: Compared to traditional copper TSVs, CNT-filled TSVs have lower CTE, better matching the thermal expansion of silicon, and exhibit superior anti-electromigration capabilities at high current densities.

Graphene-CNT Hybrid Heatsinks/Radiators: Combining the advantages of both, achieving efficient multidimensional heat dissipation.

CNT Array TIMs: Utilizing vertically aligned CNT arrays as TIMs promises to achieve extremely low interfacial thermal resistance.
