Whiskers areRefers to a fibrous one-dimensional material formed in a single crystal structure with a certain aspect ratio. Due to its relatively ideal single-crystal structure and highly ordered atomic arrangement, the defects in the whiskers are minimized, resulting in outstanding mechanical properties and functional characteristics. When used as a reinforcing modification material, it can significantly improve the mechanical strength and toughness of composite materials. Additionally, as a typical one-dimensional single-crystal material, whiskers also exhibit exceptional advantages in functional properties such as heat transfer and electrical conductivity. Boron nitride ceramics possess excellent properties such as high-temperature resistance, oxidation resistance, chemical corrosion resistance, and neutron absorption, along with low dielectric constant and dielectric loss. They have important applications in cutting-edge fields such as thermal protection coatings for carbon fiber surfaces and atomic reactors. Boron nitride whiskers combine the excellent properties of boron nitride ceramics and whisker materials, making them highly valuable in the fields of composite materials or functional materials. In particular, hexagonal boron nitride, due to its layered structure being very similar to graphite, is often referred to as "white graphite." However, compared to graphite, hexagonal boron nitride exhibits greater physical and chemical stability. Its oxidation resistance at high temperatures is exceptional, making it an ideal thermal protection material for advanced composite materials like carbon fibers. Interestingly, while most materials with excellent thermal conductivity also tend to have good electrical conductivity, hexagonal boron nitride, despite its very high thermal conductivity, is non-conductive. This makes it highly valuable for functional applications such as heat dissipation in integrated circuit substrates. Therefore, the acquisition and application of boron nitride whiskers represent a significant direction in materials science and engineering.One of the important objects of attention.
