METHOD FOR PREPARATION OF STABLE METAL OXIDE NANOPARTICLES SUSPENSIONS

摘要

The invention relates to a method for the preparation of stable suspensions of metal oxide nanopareticles, in which uncharged metal oxide nanoparticles are first treated with a non-ionic surfactant in a polar organic solvent under certain conditions, and the suspension obtained is then treated with a charging solution. The suspensions of the invention can be used for preparation of high quality metal oxide films by electrophoresis deposition (EPD).
