摘要：

A stable CdS nanoparticle hydrosol was prepared upon addition of mercaptoacetic acid as a stabilizer agent. The carboxylic groups from the mercaptoacetic acid modified on the surface of the particles resulted in an anionic surface of the CdS particles. Using an ionene (1-6-Me-BF4) as the oppositely-charged species, the anionic CdS particles were intercalated based on electrostatic interactions. The UV-Vis and quartz crystal microbalance (QCM) results proved that the CdS nanoparticles were assembled successfully. The monolayer coverage was estimated to be about 39.8% by the QCM method.
