ELECTRICAL AND STRUCTURAL-PROPERTIES OF AR-6 FILMS( IMPLANTED NYLON)

The changes in the structural and electrical properties of nylon-6 fil ms after implantation with an inert gas ion such as Ar+, with energy o f 285 keV and at different dose rates (10(14) to 10(17) ions cm(-2)), have been investigated. The conductivity, calculated using the project ed range as the thickness of the implanted layer, increases by about f our to five orders of magnitude for a dose rate of 5 x 10(15) ions cm( -2). This is the result of the formation of dangling bonds and free ra dicals due to implantation. The concentration of free radicals at room temperature measured using an electron spin resonance spectrometer sh ows that it is proportional to the dose rate up to a certain value, be yond which irradiation-induced damage sets in. The Fourier transform i nfra-red absorption spectra of the samples indicate certain structural changes due to ion implantation.
