説明

Fluorine-carbon fiber intercalation compounds were prepared in the presence of lithium fluoride, and their electrical conductivity and air stability were investigated. Most of the prepared compounds were the mixture of 2 nd and 3 rd stage, C₈∼₁₀F (d_cpu=9.4, 12.7Å) or the 3 rd stage, C₁₀∼₁₃F (d_cpu=12.7Å). The 3 rcl stage compound gave the highest conductivity of 2.5×10⁴S⋅cm^-1 which was 8 times higher than that of pristine pitch fiber, 3.1×10³S⋅cm^-1. The air stability of the compound increased with increasing intercalated fluorines. ThE electric conductivity of C₈.₈F decreased by 22% after 80 d and by 28% after 200 d. The change in the X-ray diffraction lines coincided with the decrease in the electric conductivity.
