Abstract

The present work is devoted to the theoretical study of the colloid nanoparticle interaction. A simple analytical model for the multi-particle interaction between the amphoteric oxide nanoparticles with low surface potential has been developed. The model utilizes the framework of the DLVO (Derjaguin, Landau, Verwey, Overbeak) theory and accounts for the surface charge regulation during the multi-particle interaction. The results of this study demonstrate a good qualitative agreement with the experimental data and reveal the presence of the orientation effects during nanoparticle aggregation, which may cause the formation of aggregates with different morphologies.
