Comparison of the surface properties of graphite, carbon black and fullerene samples, measured by inverse gas chromatography Original Research Article

Three types of carbon were examined by inverse gas chromatography (IGC), at infinite and finite concentration conditions: graphite, carbon black and fullerene (C60) samples. Those samples differ by their structure and also by their surface properties (existence of defects, of polar surface groups...): surface free energy characteristics and surface energetic heterogeneity. IGC allows to determine in part these properties and evidences strong differences amongst the 3 carbons.
