Abstract

The invention relates to a method for testing a temperature characteristic of a carbon nanometer pipe. The method combines quantum mechanics and molecular dynamics and utilizes the theories like the density functional theory, the electrical conductivity of the carbon nanometer pipe at different temperatures is tested from the molecule level to the atom level, and therefore the temperature characteristic of the carbon nanometer pipe is obtained. From the view of quantum mechanics, the method of molecular dynamics is combined, the actual conditions of the structures of molecules in different environments are simulated through the molecular dynamics firstly, time and labor are saved, then the temperature conductivity of the molecules are calculated through the quantum mechanics, the test result can be obtained rapidly and accurately, and the method is simple and effective.

Description

technical field [0001] The invention relates to carbon nanotubes, in particular to a method for testing the temperature characteristics of carbon nanotubes. Background technique [0002] Carbon nanotubes are a new type of nanoscale material. Due to their many excellent properties, such as: super mechanical properties, good electrical conductivity, good electromagnetic properties, good optical properties, and good adsorption and catalytic properties, It has been widely used in chemical, biological, agricultural and aviation fields. The modified carbon nanotubes modified with hydroxyl groups have good temperature characteristics, which can be applied to many occasions, such as temperature sensors and the like. However, for nanoscale carbon nanotubes, it is still very difficult to test their temperature characteristics experimentally. In the experiment, the temperature characteristics of carbon nanotubes are generally tested at a set temperature, and the temperature and condu...
