Studies on ethylenediamine-graphite oxide complexes—Structural parameters and interlayer area

Abstract

Natural and synthetic graphites were oxidized using the Staudenmaier reagent. The most strongly oxidized products were graphite oxides and the others contained both graphite and graphite oxide. Ethylenediamine was intercalated by imbibing the graphite oxidation products in liquid ethylenediamine and outgassing to constant weight. X-ray diffraction diagrams and IR absorption spectra of the adducts have been studied. The intercalated ethylenediamine exhibits little interaction with the functional groups of the layers. Its state is similar to that of liquid ethylenediamine at 20°C.
