- Abstract
- We carried out electrochemical functionalization of single-walled carbon nanotube mats (buckypaper) in HCl and KCl aqueous solutions by exposing them to electrochemical potentials above the Cl- oxidation potential and high Faradaic currents. Formation of C-Cl covalent bonds was established by X-ray Photoelectron Spectroscopy (XPS). Combining results from Raman. XPS and conductivity measurements, we find a significantly higher degree of covalent functionalization in the HCl solution as compared to the KCl one. We also discuss the impact of electrochemical doping and functionalization on the morphology and the conductivity of the SWNT sample. (C) 2008 WILEY-VCH Veriag GmbH Co. KGaA, Weinheim
