Analysis of the Size of Two-Component C₆₀-C₇₀ Fullerene Whiskers

Abstract

C₆₀-C₇₀ two-component fullerene whiskers were synthesized by a liquid-liquid interfacial precipitation (LLIP) method using various ratios of C₇₀ to C₆₀, and were analyzed for their dimensions using scanning electron microscopy (SEM). The diameters and the lengths of the C₆₀-C₇₀ fullerene whiskers show ever-increasing W-type graphs which have two local minimal values, respectively. The shape of the graphs were resulted from changing of crystal growth rate with varying of fullerene compositions of mother solution. The carcinogenicity of C₆₀-C₇₀ fullerene whiskers can be evaluated using the C₆₀-C₇₀ fullerene whiskers whose dimensions and physical factors are specified, and they will be applied to various products such as the active layer materials of solar cells and the anchor materials.
