Everyone has a strong homesickness, everyone has a nostalgia that cannot be given up, and everyone has a beautiful hometown that can never be loved. In order to enrich the working and living forms of the company's employees, KELAIWEI company carried out the photography activity of "Da Mei hometown · take photos in spring. This photography activity not only enhanced the working friendship between the new and old employees in each department of KELAIWEI company, but also enriched the humanistic culture of the company.
For the classification of carbon-based nanocomposites, carbon nanotubes are divided into different types according to different standards. Carbon nanotubes are formed after the graphene sheets are curled. Therefore, if we divide them according to the number of layers of graphene sheets, we can divide them into single-walled carbon nanotubes and multi-walled carbon nanotubes. According to the internal structural characteristics of carbon nanotubes, carbon nanotubes can be divided into sawtooth-shaped carbon nanotubes, armchair-shaped carbon nanotubes and other types.
What are the manufacturing methods of carbon nanotubes? Since the discovery of carbon nanotubes, the research on carbon nanotubes has never stopped. Carbon nanotubes have complex and excellent properties. It is both conductive and conductive, very thin but very hard, which is comparable to a hundred times of the hardness of steel. Carbon nanotubes are widely used, so various preparation methods have also been invented. Common production methods include arc method, catalytic thermal decomposition method, hydrothermal method and chemical vapor deposition method, etc.
The specific surface area of ordinary carbon nanotubes is generally 200-300m2/g, and the specific surface energy of the material is also larger. The material is more likely to be agglomerated to reduce the surface energy. The specific surface area of whisker carbon nanotubes is 13-50m2/g, the material with lower specific surface area has lower surface energy, and the material is less prone to agglomeration, which is more conducive to the dispersion of whisker carbon nanotubes on the composite material. Only the performance of dispersed carbon nanotubes can be reflected, whisker carbon nanotubes are more conducive to the development of material characteristics.
