Abstract

This study evaluates the feasibility of scattering-based diagnostics for characterizing the morphology of crumpled graphene-related two-dimensional materials in the aerosol phase. Few-layer graphene and graphene oxide are aerosolized from liquid dispersions and investigated using wide-angle light scattering (WALS). Angle-resolved scattered intensities measured for different polarization configurations yield ensemble-averaged scattering matrix elements and depolarization ratios over scattering angles from 15° to 165°. The measurements are used to assess whether crumpled graphene particles can be distinguished from fractal-like carbon-black aggregates. Simulations reported in the literature predict a characteristic non-zero depolarization at forward scattering angles for crumpled graphene structures; however, this feature is not observed experimentally. Simulation results suggest that forward depolarization depends sensitively on the degree of particle crumpling. These findings provide insight into the relationship between particle morphology and scattering behavior and highlight opportunities and limitations for optical diagnostics of graphene-based aerosols.
