Chemical Functionalization of Inner Walls of Carbon Nanotubes with Long-Chain Aliphatic Amines

摘要

In this work, we will explore the possibility of solvent-free functionalization of inner surfaces of (CNTs) with amines of different structure. This method can generate CNTs useful for many applications especially, molecules transport properties of CNT membranes and drug delivery using liberated CNTs. The structural and chemical composition of the functionalized CNTs was analyzed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR), which confirm successful and specific inner functionalization of CNTs.
