Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The method flow chart of the present invention's test carbon nanotube temperature characteristic is as follows figure 1 As shown, the specific implementation process is as follows:

[0034] 1) In this implementation process, single-walled carbon nanotubes with chirality (9,9) are taken as an example. In order to better verify the temperature characteristics of (9,9) modified carbon nanotubes modified with hydroxyl functional groups, the present invention In the scheme, the modified carbon nanotubes modified with 2 functional groups and 10 functional groups were selected for testing. figure 2 and image 3 Schematic diagrams of the models built with Materials Studio software for modified carbon nanotubes with 2 functional groups and 10 functional groups (9,9), respectively.

[0035] 2) In order to ensure the accuracy of the results, t...

Abstract

The invention relates to a method for testing the temperature characteristics of carbon nanotubes. The method combines quantum mechanics and molecular dynamics, and uses density functional theory to test the conductivity of carbon nanotubes under different temperature conditions from the molecular level to the atomic level. , so as to obtain its temperature characteristics. From the perspective of quantum mechanics, combined with the method of molecular dynamics, the present invention first uses molecular mechanics to simulate the real structure of molecules in different environments, saving time and effort, and then uses quantum mechanics to calculate its temperature and conductivity properties, so that it can be quickly and accurately The method is simple and effective to obtain test results.

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...
