采用正交试验设计方法优化反应条件制备了纯1阶结构的钾-四氢呋喃-石墨插层化合物(K-THF-GIC),研究了1阶K-THF-GIC在空气中放置、溶剂洗涤以及加热处理时的稳定性,并对K、THF嵌入石墨层间以及从石墨层间脱嵌的过程进行了探讨.结果表明:制备K-THF-GIC时,插层剂浓度和插层反应时间对产物结构的影响很大,较大的插层剂浓度,较长的反应时间有利于石墨反应完全;1阶K-THF-GIC的稳定性较差,K、THF容易从层间脱嵌,使得阶结构由1阶向高阶变化,高阶K-THF-GIC的稳定性相对1阶K-THF-GIC来说要好一些,即形成高阶K-THF-GIC后,K、THF从层间脱嵌的速率要慢些.
