GB/T 19619 and GB/T 6425-2008 and defined the following terms and definitions apply to this document.
3.1
Temperature oxidation of carbon nanotubes oxidationtemperatureofcarbonnanotubes
T0
Carbon nanotubes in air mass loss rate to the maximum value [| dm/dT | max] When the corresponding temperature.
3.2
Ash content ashrelativecontent
Rres
Quality and initial mass ratio of carbon nanotube thermal analyzer crucible residual material after full oxidation of carbon nanotubes.
Principle 4
TGA nanotubes refers to a sample of carbon nanotubes in an air atmosphere, with temperature changes in their physical and (or) chemical changes caused by the sample
Changes in quality, with a thermal analyzer recording quality and the relationship between the sample temperature, ie, thermal gravimetric (TGA) curve. For the quality of the differential temperature to give
Mass change rate (| dm/dT |) with variation of temperature, ie differential thermogravimetry (DTG) curve. Sample mass loss rate in air
Rate Max [| dm/dT | max] is defined as the temperature corresponding to the temperature of the test sample is oxidized, after full oxidation of carbon nanotubes remaining residue
Quality carbon nanotubes initial mass ratio is defined as the ash content of the carbon nanotubes.
