Boron nitride nanotubes (BNNT) have excellent comprehensive properties and huge potential for future industry development.

Boron nitride nanotubes, referred to as BNNT, refer to cylinders composed of hexagonal boron nitride with nanometer-scale diameter and micron-scale length. There are various production methods for boron nitride nanotubes, mainly including pyrolysis method, template method, ball milling method, arc discharge method, chemical vapor deposition method, oxide-assisted growth method, etc.

Boron nitride nanotubes and carbon nanotubes are both new generation nanoscale materials. They have similar structures but greatly different properties.

Specifically, in terms of structure, boron nitride nanotubes (BNNTs) are similar to carbon nanotubes (CNTs), and there are three main types of structures: armchair type, zigzag type and chiral type.

In terms of performance, compared with carbon nanotubes, boron nitride nanotubes have stronger high-temperature oxidation resistance and can withstand temperatures above 900°C in the air. Their high-temperature oxidation resistance is twice that of carbon nanotubes; boron nitride nanotubes The tube has better chemical stability and can be used in harsh environments with high temperatures and chemical activity. Its thermal neutron absorption capacity is 200,000 times that of carbon nanotubes; in addition, boron nitride nanotubes have better electrochemical properties. Mechanical properties, wetting properties, processing properties, etc., the comprehensive performance is stronger and the application range is wider.

According to the “China Boron Nitride Nanotube (BNNT) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that boron nitride nanotubes can be used as fillers for high-performance shielding materials and high-wear-resistant composite materials in production scenarios such as bulletproof vests, space suits, and human protective equipment; they can also be used as thermal interface materials in new energy vehicles. Coolant production scenarios can achieve the effect of rapid heat dissipation of batteries; it can be used as high-temperature resistant materials in electric vehicle charging interface manufacturing scenarios. The terminal fields include new energy vehicles, textiles, aerospace, national defense, clean energy, biomedicine, etc., and the market The demand is relatively broad.

Boron nitride nanotubes are a new generation of nanomaterials. The industry is still in its early development stage. The global boron nitride nanotube market size in 2022 will be around US$50 million, and the market is still relatively small. The main reason is that there are still relatively few companies in the world with mass production capabilities of boron nitride nanotubes. Only three countries, the United States, Australia, and South Korea, have successfully implemented boron nitride nanotube mass production technology. The global output is still relatively small. Low.

However, in the context of the growing potential of the boron nitride nanotube industry, it has now become a key layout area for domestic and foreign companies, and the industrialization process is accelerating. Domestic enterprise Shanghai Boron Moment New Material Technology is actively developing the boron nitride nanotube market. It has become the fifth company in the world and the first in the country to engage in the research and development, production and sales of boron nitride nanotubes. In March 2023, the company The company launched China’s first boron nitride nanotube production line. Industry analysts people said that in the future, as the construction process of domestic boron nitride nanotube projects continues to accelerate, my country’s It is expected to occupy the first-mover advantage in the boron nitride nanotube market, and the industry has broad prospects for development.
