dc.description.abstract | Sedimentation stability of iron nanoparticles (FeNPs) in low viscosity, volatile organic solvents such as ethanol and MEK is crucial for the high-quality production of FeNP-based electronics. Adding dispersants represents nowadays the common strategy to improve the sedimentation stability of FeNPs, but suffers from toxicity and high costs. Here, we present a simple vacuum drying process for enhancing the sedimentation stability of FeNPs in ethanol without using dispersants. In-situ light transmission and scattering detection showed that vacuum-dried FeNPs in ethanol and MEK sedimented much slower than those of non-treated FeNPs. The cause for the enhanced sedimentation stability was explained by Stoke's law and inter-particle attraction force change due to the reduced hydroxyl groups by the vacuum annealing. A systematic analysis of the FeNP surfaces before and after annealing provided a detailed picture of the advantages to carry out a simple vacuum annealing process to improve sedimentation stability. © 2022 The Authors | - |
