Abstract

The invention discloses a fractional order capacitor. The fractional order capacitor is defined as having an adapted dielectric impedance. To obtain the required impedance of the dielectric layer, conductive nanofillers are added to the dielectric, therefore resulting in the formation of a dielectric nanocomposite layer. In the invention a polymer matrix (like PVDF-TRFE) is combine with graphene. The graphene can be partially or completely unoxidized. The invention discloses a fractional order capacitor comprising a dielectric nanocomposite layer of thickness t, comprising a first side and a second side opposite the first side, a first electrode layer coupled to the first side of the dielectric nanocomposite layer, a second electrode layer coupled to the second side of the dielectric layer, a complex impedamce phase angle dependent on at least a material weight percentage of filler material in a dielectric nanocomposite layer.
