Abstract :
A colloidal dispersion of indium tin oxide (ITO) nanoparticles in butyl acetate solvent was achieved using a milling process in which PVP or PEG were used as a dispersant. The influences of Polyvinyl pyrrolidone (PVP) and Polyethylene glycol (PEG) dispersants on the stability of ITO suspension were studied by Zeta potential value, Nano-particle size measurement and sedimentation experiment. The results indicate that PEG dispersant dosage 5.5%, PVP 3.5% of the amount of slurry when the effect of dispersion can play, but in the storage time of 30 days, the dispersing agent PVP on the stability of slurry particles better than the PEG.
