Abstract

Gas-phase synthesis of few-layer graphene and thermal reduction of graphene oxide are among the most promising routes for producing high-quality graphene-like materials in industriallyrelevant quantities, but optical diagnostics are needed to control production efficiency and yield in situ or online. This work reports wide-angle light scattering measurements of crumpled few-layer graphene and graphene oxide, along with carbon black, to assess the feasibility of scattering-based particle diagnostics for these materials. The particles of interest are first dispersed within a solvent and then reaerosolized. The angle-resolved normalized scattered intensity, depolarization ratio, and various normalized scattering matrix elements of the aerosolized particles are measured from 15º to 165º. The results underline the promise ofscattering-based diagnosticsin characterizing the size,shape, and optical properties of crumpled graphene-like materials. However, the characteristic non-zero depolarization of crumpled graphene at forward scattering angles, evident in the scattering simulations reported in the literature, is not observed.
