摘要：
The Dielectric constant of Mono Ethylene Glycol (MEG), well-known as a dielectric medium, has been enhanced sufficiently by addition of special Nanocomposite filler called Gold Nanonetworks. The gold network structure has been grown inside the ethylene glycol medium by pulsed laser (PLD) bombardment of gold. The Impedance Spectroscopy has been carried out on the fluid medium, covering a wide frequency range (100 Hz-10 MHz), for investigating the dielectrical properties of the systems. A model based on lumped circuit of capacitors and resistors was used for the analysis. Results show a huge increase in the dc dielectric constant in the mixed MEG solution. So this network is used as very good dielectric fillers which can enhance the Dielectric constant for solvents.
