Polymer–copper-modified MWNTs by radiation-induced graft polymerization and their efficient adsorption of odorous gases



Polymer–copper-modified multi-walled carbon nanotubes (MWNTs) were prepared by radiation-induced graft polymerization of epoxy-containing glycidyl methacrylate and subsequent amination and Cu complexing. Two amines, triethyldiamine and imidazol, were used as polymeric ligand compounds. The Cu-modified MWNTs were confirmed by high-resolution transmittance electron microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, and thermal gravimetric analysis. The dynamic adsorption of odor gases, such as CH3SH and H2S, on the Cu-modified MWNTs and amine-modified MWNTs was also evaluated. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
