Integrating Boron Nitride Nanotubes into Functionalized Boron Nitride/Epoxy Composites Enhances Thermal Conductivity and Other Properties

“…With the continuous miniaturization and multifunctionalization of advanced electronic devices, along with their high degree of integration, there has been a significant increase in heat accumulation. 1,2 This can lead to thermal failure and even cause the devices to burst. 3−5 Effective thermal management is thus becoming critical for ensuring the reliability, long-life, and performance of electronics.…”

“…With the continuous miniaturization and multifunctionalization of advanced electronic devices, along with their high degree of integration, there has been a significant increase in heat accumulation. , This can lead to thermal failure and even cause the devices to burst. − Effective thermal management is thus becoming critical for ensuring the reliability, long-life, and performance of electronics. , Developing a rational design of thermal management materials (TMMs) with superior thermal conductivity is an effective way to address the heat dissipation challenge . Polymer-based composites with high thermal conductivity have proven to be efficient TMM for mitigating overheating issues. ,− These composites are particularly attractive due to their low cost, chemical resistance, and ease of processing. , However, polymers typically exhibit low thermal conductivity (0.1–0.5 W/m·K), which limits their effectiveness as thermally conductive materials.…”

In-Plane Compression Properties of Continuous Carbon-Fiber-Reinforced Composite Hybrid Lattice Structures by Additive Manufacturing

“…Alomar et al proposed a lattice structure based on circular cells, where cells consist of identical circles along two vertical planes [26]. Zhang et al designed a gradient honeycomb metastructure with optimization of the module stack large mutation genetic algorithms considering the material-structure-function integration, which can achieve the structural stealth for broadband microwave absorption [27]. Zhang et al combined a vertically enhanced hourglass shape and a traditional hexagonal structure to design a novel hybrid structure, vertical strut, and hexagonal combined structures (VSHCSs) [28].…”
