Abstract

Self-assembled monolayers (SAMs) of decanoic acids were prepared on CeO ₂ nanoparticles (NPs). The dispersion of the NPs was improved by increasing the packing density of decanoic acid SAM on CeO ₂ NPs. According to our proposed criterion related to the SAM on NPs for stable dispersion in nonpolar liquids, the CeO ₂ NPs were dispersed up to 77 wt% and perfectly dispersed up to 50 wt% in cyclohexane.
