| Abstract: | MeV ions passing through polymeric films modify their electrical, optical and thermal properties and these changes are related
to changes in the chemical structure of the polymers. Ethylene vinyl acetate (EVA) films were irradiated with 3 MeV proton
beam at different fluences of 1013, 1014 and 1015 ions/cm2. AC electrical properties of pristine and irradiated samples were studied in the frequency range 100 Hz to 100 kHz by means
of an LCR meter. There is an exponential increase in conductivity with log frequency and conductivity increases as fluence
increases. The dielectric loss/constant is observed to change with the fluence. FTIR spectra reveals significant change in
intensities of functional groups at a fluence of 1015 ions/cm2 due to scissioning of polymer chains. |
