Thermally Conductive Boron Nitride Composites and Interface Materials
This community develops materials that conduct heat efficiently while remaining electrically insulating, primarily to manage temperature in electronic devices and high-performance structural components.
The research centers on hexagonal boron nitride (h-BN) as the primary filler, processed into nanosheets, nanotubes, and powders. These are integrated into polymer matrices—specifically epoxy resins, polyimides, and polydimethylsiloxane—to create composites with high thermal conductivity and low dielectric constants. A significant portion of the work involves designing the microstructure of these composites, such as aligning nanosheets or creating 3D networks, to optimize heat flow pathways. Applications explicitly named in the literature include thermal interface materials, heat sinks for 5G base stations, and substrates for printed circuit boards. Theoretical modeling using density functional theory and molecular dynamics is also a recurring method for predicting thermal transport properties in these structures.
The largest share of the community's output is found in boron research, accounting for 8.8% of all tracked boron papers, and nitrogen research, at 2.3%. Boron also contributes the highest raw paper count within this group, with 13,643 papers.
The community comprises 19,950 papers, publishing most frequently in Applied Physics Letters, Diamond and Related Materials, and Ceramics International.
Recent work continues to focus on optimizing thermal conduction pathways in polymer composites, including the use of bio-based polyimides and 3D interconnected boron nitride networks for thermal management in microelectronics.
