HIGHLY ELECTRICAL CONDUCTIVITIES OF COPPER CHLORIDE AND ALUMINUM CHLORIDE TERNARY GICS PREPARED FROM FLEXIBLE GRAPHITE SHEETS

摘要

A wide range of materials such as alkali metals and metal halides can intercalate in the interlayers of lamellar graphite to form graphite intercalation compounds (GICs). Although GICs are known to be highly electrically conductive, their instability has limited their practical applications. We previously reported that commercial flexible graphite sheets (PGS~R) can be used to prepare air-stable and highly conductive GICs [1]. Furthermore, at CARBON 2015, we reported that CuCl2-, MoCl5-, and AlCl3-CUCl2 intercalation can be used to achieve air-stable GICs [2]. We also found that AlCl3-CuCl2-GICs prepared from PGS graphite sheets (AlCl3-CuCl2-PGS herein) are one of the promising GICs for practical applications as highly electrically conductive materials. In this study, we investigated the electrical conductivity of AlCl3-CUCl2-PGS. Various reaction conditions and four kinds of PGS graphite sheets were tested to determine the highest conductivity of the GICs.
