摘要
利用Ｃｅ４＋和炭黑表面的羟甲基组成的氧化还原体系，探讨了丙烯腈在炭黑表面的接枝聚合机理．研究表明十六烷基三甲基溴化胺和硝酸的浓度以及铈离子的用量对该反应有显著的影响．经接枝改性的炭黑在四氢呋喃溶液中具有良好的分散稳定性．
Using a redox initiating system consisting of ceric ions and hydroxymethyl groups on carbon black surface,free radical graft polymerization of acrylonitrile onto carbon black surface was investigated.The concentration of surfactant CTAB,nitric acid and used amount of ceric ion had influence on the graft polymerization.According to determination of Zeta potential and analysis of FT-IR and TEM,it was suggested that there are some graft polymers on the modified carbon black surface.The dispersion of surface modified carbon black in DMF had good dispersion stability.
