The composite electroplating bath was studied bymeans of sedimentation experiments and particle-size analysis. The results showed that dispersantswith simple structure and small molecular weight could not play steric role, however, the highlydispersed and stabilized nanoparticle Ni-ZrO_2 composite electroplating bath was obtained at pHvalue equaling to 3 by adding MZS which is a kind of macromolecule dispersant with plentifulbranched chains.展开更多
