The pore structure of expanded graphite and its characterization
摘要
Abstract
The microstructure of expanded graphite(EG)has important influence on flexible graphite products,since EG is the raw material. An introduction of the macro-meso-micro pore distribution, pore size and pore shape in expanded graphite was made. The pore structure could be influenced by various factors,such as particle size,processes of oxidation and intercalation,degree of oxidation, water-washing,expansion fashion,crushing,etc. The basic principles of N2 absorption isotherms, mercury instruction porosimetry,scanning electron microscope for structure characterizations were introduced. Advantages and disadvantages of small-angle X-ray scattering,atomic force microscope, DSC thermoporosimetry,NMR cryoporometry were also summarized. Furthermore,several suggestions of strengthening the study on meso-micro pore structure of expanded graphite and integrating various characterization methods were proposed for the further research of expanded graphite and its applications in other areas.关键词
