摘要: Metacomposites have been induced widespread concern in the realization of negative permittivity. In this paper, composites with titanium nitride (TiN) particles homogeneously dispersed polyethylene terephthalate (PET) resin were prepared by high energy ball-milling and adhesive hot-pressing method. The influences TiN networks on electric dielectric properties investigated detail. With formation conductive networks, conductance mechanism changed from hopping conduction to metal-like conduction. tunable weakly permittivity radio frequency range was obtained TiN/PET adjusting volume fraction (v) composites. Negative behavior raises low-frequency plasma oscillation free electrons which could be analyzed Drude model. impedance equivalent circuit analysis, demonstrating capacitive or inductive This paper shows an effective way toward permittivity, will promote practical applications metacomposites electromagnetic shielding matching fields.
