Stabilization of Graphite Nitrate by Intercalation of Organic Compounds

A novel route towards high quality fullerene-pillared graphene

“…The final hybrid material and the intermediate products were characterized by X-ray diffraction as well as by differential thermal and thermogravimetric (DTA-TGA) analysis, in conjunction with X-ray photoelectron and Raman spectroscopies. The possibility of stabilizing graphite nitrate by intercalation of organic compounds has been tried in the past [24,25], but here we report for the first time the insertion of a robust organic molecule acting as pillar between the graphene layers to create a hybrid structure with good thermal stability.…”

The synthesis of thermally expandable residual graphite nitrate in the system HNO3-CH3COOH-H2O

“…This substitution may increase the solvation of the NO 3 -anion, which signifi cantly affects GIC stability [8]. Previously, a wide variety of the modifi ers (carboxylic acids, nitriles, ethers and esters) has been found, which increase stability of GIC based on graphite nitrate [9]. For industrial application, the most attractive modifi er is acetic acid, because of its unique stabilizing properties and accessibility.…”
