heal.abstract	The current postgraduate thesis stands as a sequel to Mr John Asimakopoulos’ (Doctor at the Chemical Engineering School of NTUA) Phd project “ Construction, Characterization and Qualities of Polymeric Matrix’s Complex Dielectric Materials”, under the supervision of Mr. Luke Zoumboulaki, who is Associate Professor of the School of Chemical Engineering of NTUA. This study consists of two parts: In the first one, the capacity ( C ) ,the impedance (Z) , the ohmic resistance ( R ) , the electric conductivity ( G ) , the capacitive response (X) and the susceptibility (B) of capacitors that have polymeric matrix’s complex materials at the nanoscale as dielectric device, is studied. In particular, the polymers that consist the polymeric matrices of these complex materials are classified to the categories of phenol formaldehyde resins (namely neolakes), unsaturated polyester and epoxy resins. All the composite materials that were used for the measurements of the above sizes have 10% w/w ceramic nanoparticles of barium titanate (BaTiO3 ) as a supplement. For conducting the above measurements required the design and construction layout that will accommodate these composites to measure the above sizes. The final result is a host impromptu arrangement of dielectrics – composites, that will have different technical characteristics by rotating each sample (SYPN) . These measurements were achieved with the aid of LCR Meter for the frequency range from 10kHz to 1ΜHz and in room conditions. (Temperature: 20 - 30 μC and humidity : 30– 40%). On the other hand, in the second part, these capacitors were used in each complex material as a dielectric for the manufacture and assembly of lowpass , highpass, bandpass and bandstop electronic filters on breadboared. Afterwards, the measurements on the cutoff frequency (f C) of lowpass and highpass filters and the bandwidth of the bandpass and bandstop filters (pass filters and stopband) took place with the aid of a generator and oscilloscope sinusoid. Measurements were obtained concerning the cutoff frequency and bandwidth of electronic filters’ rates potentiometer R: 10KΧ, 20KΧ, 50KΧ, 100KΧ, 200KΧ, 300KΧ, 500KΧ. Finally, a comparison and evaluation of the experimental measurements, as were obtained by the oscilloscope, based on the cutoff frequency and the quality factor Q of those electronic passive filters.	en
