摘要
在常温下制备可膨胀石墨的各种方法中，浓硫酸起着重要作用．研究表明：浓硫酸影响着可膨胀石墨的膨胀容积和含硫量，而它们恰是决定可膨胀石墨质量高低的重要参数．研究可膨胀石墨制备的反应机理可以得出这种影响的根本原因在于浓硫酸与石墨形成了层间化合物．
The concentrated sulfuric acid plays an important role in the preparation of expandable graphite in room temperature.The research has proved it influences the sulfur content and expanded volume of the expandable graphite.These are the impartant parameter of the expandable graphite.The mechanism of the expandable graphite has been researched to find reason,which the compound between concentrated sulfuric acid and graphite is formed.
