Abstract
The static dielectric constant ε of buckminsterfullerene C60 particles is determined in cis-decalin, toluene, and 1,2-dichlorobenzene using continuum models for spherical and sherical shell inclusions. The value for ε for isolated C60 in cis-decalin and toluene agrees well with molecular molecular beam measurements using a spherical shell model, but the ε estimate in the highly polar solvent 1,2 dichlorobenzene deviated from these other measurements. Complications of measurements in highly polar solvents are summarized. We conclude that virial measurements have a great potential for determining the effective properties of nanoparticles from the properties of nanofilled materials over a range of dilute filler concentrations.
