Energetics of Sulfur-Carbon Interaction

The energetics of sulfur-carbon interaction are studied using thermo-desorption and immersion microcalorimetry experiments. Sulfur is incorporated in meso- and microporous carbons by impregnation either from the liquid phase or the vapor phase. Varying the temperature of impregnation enables to fill preferentially microporous domains (vapor impregnation) or both micro-meso-macro domains (liquid impregnation). The three carbons lead to similar immersion enthalpies per unit area for liquid sulfur. This suggests that they possess similar surface-liquid interactions and that liquid sulfur, below the polymerization temperature, wets the whole surface accessible to nitrogen.

Automated summary

The energetics of sulfur-carbon interaction were investigated using experimental methods, and it was found that different types of carbon materials show similar surface-liquid interactions with liquid sulfur, which can wet the entire surface accessible to nitrogen.
