Boron nitride (BN) materials have unique physical, chemical, and mechanical properties, making them useful in various applications across different fields. Here are some practical examples of how boron nitride materials are utilized in daily life:

1. Lubricants and Additives

   • Hexagonal boron nitride (h-BN) is widely used as a lubricant and as an additive in cosmetics due to its structural similarity to graphite, stability, and softness. These properties make it an excellent material for reducing friction and enhancing the texture of cosmetic products (Haubner et al., 2002).

2. Thermal Management

   • BN materials are used as fillers in thermal management applications, particularly in thermoplastic compounds. They significantly improve the thermal conductivity and wear resistance of polymers, which is essential for electronic devices and other heat-sensitive applications (Raman & Meneghetti, 2008).

3. Electronics and Optoelectronics

   • Due to its wide optical bandgap, boron nitride is suitable for deep ultraviolet optoelectronic devices and high-power electronic devices. BN nanosheets are used as dielectric substrates and gate dielectric layers in graphene-based electronic devices, offering excellent insulation properties (Izyumskaya et al., 2017).

4. Environmental Protection

   • BN materials are used for removing pollutants from water due to their high surface area and chemical stability. They are effective in adsorbing heavy metals and organic pollutants, making them valuable for water purification and environmental remediation (Yu et al., 2018).

5. Biomedicine

   • Boron nitride nanomaterials are explored for drug delivery, imaging, and cell stimulation due to their biocompatibility and stability. They have shown promise in various biomedical applications, providing safe and efficient means for medical treatments (Merlo et al., 2018).

6. Batteries

   • BN nanomaterials are incorporated into lithium-ion and sodium-ion batteries as components of electrolytes, separators, and electrodes to enhance battery performance and stability. These materials help in improving the efficiency and lifespan of batteries (Mateti et al., 2023).

7. Cosmetics

   • Due to its stability and softness, boron nitride is used as an additive in cosmetic products, enhancing their texture and feel, and improving the overall user experience (Raman & Meneghetti, 2008).

Conclusion

Boron nitride materials have diverse and valuable applications in daily life, from electronics and thermal management to environmental protection and biomedicine. Their unique properties, such as high chemical stability, thermal conductivity, and biocompatibility, make them suitable for a wide range of practical uses.
