Dielectric Parameters of Polystyrene Films Modified with Fullerenes

摘要

The frequency dependences of the electrophysical parameters (capacitance, dielectric constant, dielectric loss tangent, and resistivity) of polystyrene films doped with small (up to 1 wt C_(60)) additions of fullerenes were determined by dielectrometry. The composite materials obtained were concluded to be nonpolar. The dielectric constant as a function of the film composition passes through a minimum at 0.035 wt C_(60). The polymer preserves good insulating properties on doping with fullerenes.
