Abstract
We have synthesized K-CFICs by the modified two-bulb method. These synthesized compound were analysed with X-ray diffractometer and UV/VIS spectrophotometer. According to X-ray diffraction analysis, the intercalation of potassium between the carbon layers of carbon fiber was better then other intercalants. From obtained data for this deintercalation process, we can see that a number of potassiums were presented as a residue between the carbon layers and this residue compounds had a stability for a long term. Therefore, it is appear that these compounds have a capability as new useful material. From UV/VIS spectrometry data, we can suppose that spectrum of K-CFICs synthesized at
변형된 two-bulb법에 의하여 K-CFICs를 합성하였다. 합성된 화합물은 X-선 회절법과 UV/VIS 분광기에 의하여 분석하였다. X-선 회절법에 의하면 탄소섬유의 칼륨을 삽입시킬 때 다른 삽입물질보다 Intercalation이 잘 이루어짐이 나타났다. 이들의 Deintercalation 과정에 대한 분석을 한 결과 칼륨이 탄소섬유층 속에 상당히 잔류하고 있었으며, 뿐만 아니라 이들 화합물은 상당 기간 안정성을 보이고 있었다. 따라서 새로운 재료로서의 이용 가능성을 보여 주고 있다. UV/VIS 결과에 의하면
