石墨是层状结构.许多分子、原子和离子能渗入层间,形成插入化合物(Interca-laton compound)或称层状化合物(lamellar compound).从第一个合成石墨插入化合物至今已一个多世纪了.作第一次系统研究(X射线衍射测定级数)至今也已五十多年了.由于新技术发展的需要,最近几年,人们不仅对其结构、物性等理论问题进行探讨,更着重于挖掘其作为功能材料的应用价值.石墨插入化合物已成为化学家、物理学家和材料科学家研究的热点之一. Graphite is a layered structure in which many molecules, atoms and ions can penetrate into layers to form an intercalated-laton compound or lamellar compound. It has been more than a century since compounds were first inserted into synthetic graphite For the first systematic study (X-ray diffraction measurement series) has so far been more than 50 years due to the needs of the development of new technologies, in recent years, people not only on its structure, physical properties and other theoretical issues to be more focused Digging its value as a functional material.Graphite insertion compounds have become one of the hot topics for chemists, physicists and material scientists.
