【 摘 要 】

The assembly of colloidal particles into ordered structures is of great importance to a variety of nanoscale applications where theprecise control and placement of particles is essential. A fundamental understanding of this assembly mechanism is necessary to notonly predict, but also to tune the desired properties of a given system. Here, we use constructal theory to develop a theoreticalmodel to explain this mechanism with respect to van der Waals and double layer interactions. Preliminary results show that the particle aggregation behavior depends on the initial lattice configuration and solvent properties. Ultimately, our model provides thefirst constructal framework for predicting the self-assembly of particles and could be expanded upon to fit a range of colloidalsystems.
