Using first-principle calculations, we have investigated the chemical functionalization of (8,0) zigzag single wall carbon nanotubes (SWNTs) by the amine group on Stone–Wales (SW) defects. The binding of NH2 with the defective (8,0) nanotube was ex

Publikováno v: Computational and Theoretical Chemistry. 967:231-234

Using ab initio calculations, we have investigated the sidewall functionalization of several (n, 0) zigzag single wall carbon nanotubes (SWCNTs) by the amine group with n varying from 5 to 23. The results show that the stability of the NH2 group depe

This article proposes an alternative way to use carbon nanotubes to improve the performance of carbon fibre-reinforced composites. A chemical process, based on esterification of surface groups, is used to anchor nanotubes onto carbon fibre surface. A

A chemical method to graft carbon nanotubes onto a carbon fiber

Autor: Christophe Poilâne, Jun Chen, Jin Bo bai, M’hamed Ayachi, Abdelghani Laachachi, Bessem Ben Doudou, Gerard Nouet, Alexandre Vivet

Publikováno v: Materials Letters. 62:394-397

A simple method is developed for grafting carbon nanotubes (CNTs) onto a carbon fiber surface. CNT and carbon fiber undergo an oxidation treatment. Oxidation generates oxygen, like carboxyl, carbonyl or hydroxyl groups, or amine groups on nanotubes a
