Self-assembly of delaminated layered double hydroxide nanosheets for the recovery of lamellar structure

The aggregation mechanism of delaminated layered double hydroxide (dLDH) to form lamellar or even more complex nanostructures is revealed. It is found that dLDH nanosheets undergo ordered restacking via self-assembly upon salt induced aggregation within a short period of time. This first step is fol...

Summary:The aggregation mechanism of delaminated layered double hydroxide (dLDH) to form lamellar or even more complex nanostructures is revealed. It is found that dLDH nanosheets undergo ordered restacking via self-assembly upon salt induced aggregation within a short period of time. This first step is followed on longer term by the formation of house-of-cards-type aggregated clusters. [Display omitted] •Monodisperse 2-dimensional dLDHs synthesized with a simple aqueous phase process.•Two-steps aggregation mechanism proposed and proved for dLDH dispersions.•Electrolyte induced aggregation of dLDHs quickly recovers lamellar LDHs.•Evolution of clusters observed over longer periods and/or high salt concentrations.•Stability of dLDH dispersions quantitatively assessed.
