Semiconductor: Carbon nanotubes have the characteristics of high crystallinity, good electrical conductivity, large specific surface area, micropore size can be controlled by synthesis process, and specific surface utilization can reach 100%. Wide bandgap semiconductors, which can greatly reduce energy consumption in power transmission, are becoming the focus of research in China's semiconductor industry. The carbon nanotubes used in wide-gap semiconductors have ultra-thin conductive channels, extremely high carrier mobility and stability, and are expected to replace traditional silicon-based integrated circuit technology. At present, wide bandgap semiconductors have been widely used in automotive, health and other fields.

Easy to lose parts coating: Single-wall carbon nanotubes have stable chemical properties, extremely high mechanical properties and electrical conductivity, can be used as the coating of easy to lose parts of aircraft, enhance the wear resistance, erosion, corrosion, permanent and stable resistivity of easy to lose parts, improve the service life of easy to lose parts and antistatic performance.

Automotive paint: The high electrical conductivity and mechanical properties of single-wall carbon nanotubes can be used for automotive paint and electronic spraying, so that car companies have good anti-static performance and wear resistance, improve the service life of automotive paint, and have a variety of colors to choose from, and make the car have good flame retardant.

Heat dissipation material: Single-wall carbon nanotubes have extremely high thermal conductivity, and their thermal conductivity can reach 6000W/m.K, which is 10-20 times that of copper. It can therefore be used to:

1. Aircraft engine operation will produce extremely high heat, the temperature can reach 1400-1700℃, high requirements for heat dissipation, adding a single wall carbon nanotube thermal conductivity coating, thermal conductivity can be increased by more than 30%, can quickly reduce the temperature of the engine, improve the safety of operation.

2. When an aircraft flies through clouds with temperatures below zero, supercooled water droplets can form ice on surfaces such as wings, propellers, or engine air intakes, causing increased drag and significantly reducing lift, making the aircraft difficult to control. The excellent thermal conductivity of single-walled carbon nanotubes can be used for deicing, and lightweight resistance heaters based on carbon nanotubes (CNTs) can be used to prevent the icing and deicing of composite aircraft. When used on passenger aircraft using carbon fiber reinforced polymer composites (CFRP), the weight is negligible, the heating is fast and uniform, the energy consumption is low, the compatibility with CFRP is high, and the adjustment can be made to achieve rapid anti-freeze and de-icing.

Tire application: The tensile strength of single-wall carbon nanotubes is more than 100 times that of steel, but the density is only 1/6 of steel, with ultra-light weight and ultra-high mechanical properties.

Aircraft tires, car tires: By adding single-wall carbon nanotubes and rubber composite, the super-strong mechanical properties of single-wall carbon nanotubes can improve the wear resistance of tires, so that the production of aviation tires has anti-static, high load, impact resistance, low heat generation, high wear resistance and other functions, so that the static charge generated by tires during takeoff and landing can be evenly transferred to the ground, which can improve the service life of aircraft tires. It also saves manufacturing costs. Adding less than 0.05% of single-wall carbon nanotubes is enough to improve the mechanical properties and electrical conductivity of the tire. The wet grip is more than 15% higher than the existing similar tires, and the weight of the tire can be significantly reduced, while improving the flexibility and elasticity of the rubber tire and achieving conductive or antistatic performance, improving the mechanical properties of the tire such as energy efficiency, stiffness and wear resistance, improving hardness, heat resistance and extending the service life.

Pressure vessels: Oxygen masks and cylinders: Single-walled carbon nanotubes are ideal for use as oxygen masks and cylinders in aircraft. Their low density makes the cylinders lighter, and their high mechanical properties make it possible to protect the escape system from damage in the event of an impact.

Automobile manufacturing: body panel, floor assembly, seat panel assembly, rear floor beam assembly: carbon nanotubes are embedded in the all-aluminum body, which is more than 30% lighter than aluminum alloy, and compared with the same volume of high-strength steel, the weight is only 1/5 of it. At the same time, the rear floor assembly, seat board assembly, and rear floor beam assembly can all be made of carbon nanotube material. The rear floor made of carbon nanotube can make the overall torsional rigidity of the body higher, improve the passive safety performance, and greatly improve the overall durability.

Flame retardant material: The rapid heat dissipation ability of the rice tube, even if the extreme high temperature, the carbon nanotubes in the coating are completely scorched, this scorched layer also has a stable flame retardant structure, can form a carbon protective layer to prevent the flame from continuing to spread. The ultra-high electrical conductivity and ultra-light characteristics of single-wall carbon nanotubes can improve the anti-static performance of synthetic aircraft leather, reduce the weight of synthetic leather, reduce fuel consumption, and reduce the cost of airlines.
