Yesterday we talked about the new wonderful properties of graphene. No less interesting is also other material of carbon - carbon nanotubes . Each such tube - this is the same graphene, only a rolled. The length of the tubes may be in almost any reasonable limits. NEC Company, for example, uses nanotubes composed of a special paint and already knows how to literally print on special printer transistor gate. But in order to move the process of using nanotubes to laboratories and to begin mass production of the new material, we need special techniques. One of these technologies, according to Japanese sources, the company has offered Meijo Nano Carbon in collaboration with the Institute of National Institute of Advanced Industrial Science and Technology (AIST).
More or less detail about the method of mass production of the material based on carbon nanotubes described online AIST. We will not go into much detail. Only explain that the proposed method is a form of CVD (chemical vapor deposition) - chemical vapor deposition (CVD). Something is injected into the chamber, and burned . For the production of carbon nanotubes by the acronym tested process eDIPS (Direct Injection Pyrolytic Synthesis) .
Work on the factory showed that the process of production of materials based on carbon nanotubes can be accelerated by more than 100 times. What is important, while maintaining stable characteristics of the material. This figure was 20-50 times better than with other methods of producing carbon nanotubes. On the photo above you can see the 15-cm "pancake" with a 99% purity of the material, the thickness of which corresponds to block a single nanotube. Characteristics of the samples were tested for Raman spectroscopy. Scientists have confirmed that the material quality has improved significantly, and it promises to transfer technology industrial rails. Related Products :
