2.Shenzhen Topology Precision Film Technology Co., Ltd. is specialized in Industry and agriculture,Machinery and industry equipment,Industry-specific equipment supply since established in 10 years ago.So far,our company has established its branch companies in major cities throughout the country.Formed in 4th Floor, Building 1, Tingwei Industrial Park, No. 6 Liufang Road, Xin'an Street, Bao'an District, Shenzhen, China,Bao'an District,Shenzhen City,Guangdong Province,China as the center, the radiation sales system and service network.Details:4.As a one-dimensional nanomaterial, carbon nanotube is light in weight, hexagonal structure is perfectly connected, and has many abnormal mechanical, electrical and chemical properties. In recent years, with the deepening of research on carbon nanotubes and nanomaterials, its broad application prospects are constantly being revealed.Carbon nanotube, also known as bucky tube, is a one-dimensional quantum material with a special structure (radial size is nanometer-scale, axial dimension is on the order of micrometers, and both ends of the tube are substantially sealed). The carbon nanotube is mainly composed of a plurality of coaxial tubes of a plurality of layers of carbon atoms arranged in a hexagonal shape. The layer maintains a fixed distance between the layers, about 0.34 nm, and the diameter is generally 2-20 nm. And according to the different orientation of the carbon hexagon in the axial direction, it can be divided into three types: zigzag, armchair and spiral. Among them, the spiral type carbon nanotube has chirality, and the zigzag and armchair type carbon nanotubes have no chirality.On October 27, 2017, the World Health Organizations International Ag |
