The research and development cycle of whisker carbon nanotubes is long, and it is not easy to achieve a breakthrough in a short time. Ordinary carbon nanotubes all use solid catalysts to deposit the catalysts on the surface of carrier materials, carbon nanotubes are synthesized by introducing hydrocarbon gas after calcination and reduction. Compared with traditional carbon nanotubes, the process technology of whisker carbon nanotubes is more complicated. In the process of synthesizing whisker carbon nanotubes, improper regulation may lead to the growth of non-linear ordinary carbon nanotubes, the product has high requirements for process control.

Carbon nanotubes have been widely used in the manufacture of flexible electronic devices and precision sensors. High purity, high density carbon nanotubes with its excellent conductivity and thermal conductivity characteristics, the characteristics such as ultra-high conductivity and the toughness which is 100 times the strength of steel have become very important materials for precision sensors and modern high-end flexible electronic devices. Carbon nanotubes have become the main products of Henan KELAIWEI Nano Carbon Material Co., Ltd.
A brief introduction to the study of carbon nanotube catalyst carrier materials. Carbon nanotubes have very good photoelectric properties, and the specific surface area of carbon nanotubes is very large. Due to the large amount of active site eggs on the surface of carbon nanotubes, they are widely used as catalyst carriers. The academic research of carbon nanotube catalyst carrier pays special attention to the catalytic value of excellent electrical properties of carbon nanotubes, the influence of unique tubular structure of carbon nanotubes on catalysis, the influence of carbon nanotubes with extremely rich hydrogen storage characteristics on catalysis and other fields.
The disadvantage of graphene electric ground heating, the purity of carbon nanotubes reflects the technological level of the product, the higher the purity, the greater the difficulty of the process, the metal impurity content of ordinary carbon nanotubes is generally above 200ppm, through the high temperature purification process of 3000 ℃, the whisker carbon nanotubes are put into the furnace by using a specific crucible, and the purification time is more than 10 hours. The metal impurities inside the carbon nanotubes can be completely vaporized, the content of metal impurities can be controlled within 100ppm, the purity level is extremely high, and the use of lithium ion batteries is more assured.
