Carbon nanotubes have many excellent mechanical, electrical and chemical properties in many fields It has a wide range of application prospects and is a nanomaterial that has been industrially produced [1]. Amorphous carbon, ash, and volatiles in carbon nanotubes The content and its main oxidation temperature and thermal stability have a great influence on its performance and application [2, 3]. Therefore, the components of the carbon nanotube sample are accurate. Accurate measurement and evaluation of its oxidative and thermal stability are key control parameters for the quality of carbon nanotube samples. Thermogravimetry (referred to as TG) is to evaluate the content of different components in carbon nanotubes samples and their main oxidation temperature and heat The effective method of stability, the use of different experimental atmospheres can obtain different information [4~8]. This standard gives carbon in different experimental atmospheres Thermogravimetric analysis (TGA) techniques and specifications for nanotube samples, including different experimental atmospheres Under the TG principle and data processing process and so on. The experimental atmosphere specifically includes a carbon dioxide atmosphere, a mixed gas atmosphere of oxygen and synthetic air And nitrogen atmosphere. The formulation of this standard will provide for the production of carbon nanotube samples, testing organizations, research institutes and related supervision and management departments. The use of TG to analyze the contents of amorphous carbon, ash, volatiles and other components and oxidation temperature in carbon nanotubes under the same experimental atmosphere reference. Nanotechnology Carbon Nanotubes Amorphous Carbon, Ash, and Analytical thermogravimetry of volatiles1 ScopeThis standard specifies the use of thermogravimetric analysis of amorphous carbon, ash, and volatiles in carbon nanotube samples under different experimental atmospheres. The method for measuring the main oxidation temperature and thermal stability of the carbon nanotubes and the carbon nanotubes includes an atmosphere of carbon dioxide, a mixture of oxygen and synthetic air. Gas atmosphere and nitrogen atmosphere. This standard applies to single-wall and multi-wall carbon nanotube samples obtained by chemical vapor deposition. Carbon nanotube test obtained by other preparation methods You can refer to the implementation.2 Normative referencesThe following documents are indispensable for the application of this document.
