Abstract
An attempt was made to synthesize first stage potassium graphite intercalation compounds (K-GIC) from carbon films with thickness of only about 40 nm, which was prepared in the two-dimensional space between the lamellac of montmorillonite. For comparison, K-GIC from natural graphite flakes were also synthesized. The compounds thus obtained were characterized with X-ray diffractometer and their chemical stability was investigated. The process of potassium intercalation was discussed in relation to the change in average crystal size Lc, due to the intercalation.
