Characterization of Graphene-Nanoplatelets Structure via Thermogravimetry Academic Article uri icon

abstract

  • The rapid increase in graphene-based applications has been accompanied by novel top- down manufacturing methods for graphene and its derivatives (eg, graphene nanoplatelets (GnPs)). The characterization of the bulk properties of these materials by imaging and surface techniques (eg, electron microscopy and Raman spectroscopy) is only possible through laborious and time-consuming statistical analysis, which precludes simple and efficient quality control during GnP production. We report that thermogravimetry (TG) may be utilized, beyond its conventional applications (eg, quantification of impurities or surfactants, or labile functional groups) to characterize bulk GnP properties. We characterize the structural parameters of GnP (ie, defect density, mean lateral dimension, and polydispersity) by imaging and surface techniques, on one hand, and by a systematic TG, on the other …
