Chemical, Electrical and Morphological Properties of Kapton Polymer Irradiated by Gamma Radiation
Abstract: Kapton polymer has proven their potential in the field of electronics, space and nuclear technology, also found to have very good electrical properties, mechanical strength and high melting points (260oC to 350oC) due to the presence of aromatic ring in the polymer back bone. In this paper, we have studied the Chemical, Electrical and Morphological properties of virgin and high dose (500 - 2000 kGy) ? - irradiated samples of Kaptonpolymer. This polymer samples were analysed by using Fourier transforms infrared (FTIR) spectrophotometer, Model 1720 with 0.5 wave number resolution in the range (4300 - 500 cm - 1). The FTIR spectrum shows no major change except a small increase in the intensities of some identified band due gamma irradiation. This indicates that Kapton is radiation resistant. The dielectric study was carried out by using High Frequency Impedance Analyzer (PSM 1735) over the frequency range (10 Hz - 30 MHz) at ambient temperature. The increase in A C conductivity with radiation dose is attributed to scissioning and crosslinking on the surface of the polymer. The surface morphology of Kapton polymer was characterized by scanning electron microscope (SEM) using (JEOL, Model No.3300) operating at 30 kV accelerating voltage. The scissioning is responsible for the evolution of gases from the surface and the respective erosion.
