In order to obtain the fundamental information on the modification of polymers due to irradiation, X-ray diffraction, FTIR (Fourier Transform Infrared Spectroscopy), UV-visible spectral analysis has been employed to CR-39(Columbia Resin) polymer irradiated by IR (infrared) radiations. The effects of infrared radiations on the physical, optical and chemical properties have been reported in the present work. The results have been discussed on the basis of scission and cross linking induced in the polymer during infrared exposure and a brief mechanism has been suggested, where ever possible. The changes in intensity of FTIR absorption bands related to particular groups and bonds have been discussed. The shift in the absorption edge towards longer wavelength in UV-VIS spectra of the irradiated polymers has been observed. The crystallite size of the pristine and IR irradiated CR-39 samples has been calculated from XRD.

Abstract


In order to obtain the fundamental information on the modification of polymers due to irradiation, X-ray diffraction, FTIR (Fourier Transform Infrared Spectroscopy), UV-visible spectral analysis has been employed to CR-39(Columbia Resin) polymer irradiated by IR (infrared) radiations. The effects of infrared radiations on the physical, optical and chemical properties have been reported in the present work. The results have been discussed on the basis of scission and cross linking induced in the polymer during infrared exposure and a brief mechanism has been suggested, where ever possible. The changes in intensity of FTIR absorption bands related to particular groups and bonds have been discussed. The shift in the absorption edge towards longer wavelength in UV-VIS spectra of the irradiated polymers has been observed. The crystallite size of the pristine and IR irradiated CR-39 samples has been calculated from XRD.
