Abstract: Using a redox initiating system,which consists of ceric ions and hydroxymethylgroups on carbon black surface, free radical graft polymerization of acrylamide onto carbonblack surface was investigated.It was found that the polymerization was influenced by theconeentrations of acrylamide,nitric acid and ceric ions.The measurements of zeta electricpotential, FTIR and TEM observations showed the presence of graft polymer on the modi-fied carbon black particles,but the zeta electric potential of the particles was not changed.The surface modified carbon black particles possessed excellent dispersion stability in water.
