Electric properties of natural kaolinite and kaolinite intercalated by ethylene glycol were measured and compared. We found that the intercalation considerably increases the electric permittivity. It is explained as a possible movement of polar guest molecules in the interlayer area. The dielectric data were supported by XRD and TGA experiments.
