Area of Science:

  • Materials Science
  • Colloid and Surface Chemistry
  • Nanotechnology

Background:

  • Characterizing the aggregation behavior of two-dimensional engineered nanomaterials (2D ENMs) is crucial for understanding their environmental fate and application performance.
  • Existing methods may not fully capture the complex aggregate morphology of anisotropic 2D ENMs.

Purpose of the Study:

  • To evaluate the utility of static light scattering (SLS) for characterizing the aggregate morphology of 2D ENMs.
  • To compare the aggregation behavior of graphene oxide (GO) and lithiated-molybdenum disulfide (Li-MoS2) with spherical nanoparticles.
  • To determine the critical coagulation concentration (CCC) and fractal dimensions of these nanomaterials.

Main Methods:

  • Static Light Scattering (SLS) for aggregate morphology.
  • Time-resolved Dynamic Light Scattering (DLS) for aggregation kinetics and CCC determination.
  • Cryogenic Transmission Electron Microscopy (Cryo-TEM) for direct visualization of aggregate morphology.

Main Results:

  • SLS effectively characterized the aggregate morphology of GO and Li-MoS2, consistent with Derjaguin-Landau-Verwey-Overbeek (DLVO) theory.
  • Fractal dimension decreased with increasing ionic strength towards the CCC for all tested nanomaterials.
  • The transition from reaction-limited aggregation (RLA) to diffusion-limited aggregation (DLA) was elucidated.

Conclusions:

  • SLS is a valuable technique for measuring the fractal dimension of 2D ENMs.
  • The aggregation behavior of 2D ENMs, including GO and Li-MoS2, follows established colloidal stability theories.
  • Understanding aggregate morphology is key for predicting the behavior of 2D ENMs in various environments.
