      Carbon Nanotube

      Carbon nanotubes ("CNT") are nano-scale fibrous materials with a special graphite structure. They are hollow tubes formed by crimping a carbon six-membered ring sheet structure similar to graphite. The diameter of the tube ranges from several To tens of nanometers, the length is in the order of micrometers. According to the number of layers of graphene sheets, CNTs can be divided into multi-walled carbon nanotubes, double-walled tubes, and single-walled carbon nanotubes. The carbon-carbon sp2 hybrid bond in the graphite plane of carbon nanotubes is one of the strongest chemical bonds in nature. It forms the outstanding mechanical properties of carbon nanotubes and is an ideal mechanical reinforcement material. At the same time, the one-dimensional nanostructure of carbon nanotubes and the graphite structure of the carbon nanotube tube layer determine that they have special electrical properties and good heat transfer performance. It is precisely because of the above-mentioned excellent physical and chemical properties of carbon nanotubes that their application research has flourished in recent years, involving many fields, such as lithium ion batteries, super structural materials, conductive composite materials, thermal conductive composite materials, solar cells, field Emissions, electronics and data storage, sensors, medicine, and pharmaceuticals make carbon nanotubes the most promising nanomaterials in the 21st century.


      Lithium-ion battery field:

      In the booming field of lithium battery materials, carbon nanotubes and their composite conductive agents can further improve the performance of micron-level anode and cathode materials. The organic combination of ultra-high conductivity and positive and negative materials can effectively improve the energy density, charge and discharge efficiency, charge and discharge rate and cycle life of lithium batteries, improve the high and low temperature performance of power batteries, and accelerate pure lithium batteries. The industrialization of electric vehicles and promote the industrial upgrading of the entire lithium battery industry


      Conductive coating, plastic field:

      Conductive coatings and plastics are produced by modifying the insulating polymer medium to make them have a certain electronic transition and conductivity. This conductivity can make ordinary polymer materials antistatic, dustproof, anticorrosive, and anticorrosive. With functions such as mildew, highly conductive systems have become materials that are sought after in high-tech fields such as smart wearable devices, touch-sensitive components, and smart surfaces. At present, the main development and production at home and abroad are mainly concentrated on carbon-based filled conductive coatings and conductive plastics. The use of carbon-based conductive agents accounts for more than 70%. The mainstream filler materials are still concentrated on conductive carbon black, graphite and carbon fiber. Its high addition level makes the product inevitably face the disadvantages of the deterioration of the mechanical properties of the material. The use of nano conductive agents such as carbon nanotubes can greatly reduce the amount of conductive agent used, thereby maintaining the intrinsic characteristics of the plastic system, maintaining and effectively increasing the mechanical strength. Generally, the addition amount of carbon nanotubes is about 1-3%.


      Special rubber field:

      After effective treatment, carbon nanotubes are added to rubber, which can greatly improve the rubber's wear resistance, stretching and tear resistance. It is an ideal raw material for manufacturing special tires.


      Thermal conductive material:

      Carbon nanotubes have excellent thermal conductivity, 3000 W/m.K. Thermal conductive materials prepared by making full use of the thermal conductivity of carbon nanotubes will have unparalleled thermal conductivity, contributing to energy conservation and environmental protection, 5G communications, and extending the service life of electronic devices.
