Dispersing Agent of MWCNTs and the Method for Preparation and Application of Homogeneous MWCNTs Dispersion

Abstract

Dispersing agent of MWCNTs and the method for preparation of homogeneous MWCNTs dispersion are disclosed. Acid yellow 9(4-amino-1-1′-azobenzene-3,4′-disulfonic acid, AY) is a good agent for multi-walled carbon nanotubes (MWCNTs). MWCNTs dispersed in AY solution was remained stable about three months and even remained stable after centrifugation at 10000 rpm for 30 min. Using MWCNTs/AY dispersion, thin-films were prepared on indium tin oxide coated glass electrode and glassy carbon electrode. Further, dried firms of MWCNTs/AY were subjected to electropolymerization in 0.1 M H2SO4 solution. Adsorbed AY molecules on MWCNTs get polymerized and then yield a polymer-MWCNTs nanocomposite film on electrode surface so as to modify properties of the electrode.
