“…6.21. A significant mixing occurred at the interface evidenced by the asymmetrical broadening and the shift of the low energy edge of the Ni peak and high energy edge of the F peak [602]. Irradiation of different polymers by Bi ions of 1.1 GeV in the range between 10 7 and 10 14 ions/cm 2 have been used as a dedicated tool to modify their surface properties.…”

The present work envisages synthesis of magnetic nanocomposites by ion beam mixing technique using swift heavy ion irradiation of Ni-Teflon bilayer system and its magnetic characterizations. The nanocomposite is characterized by Rutherford backscattering spectrometry (RBS), transmission electron microscopy (TEM), scanning probe microscopy (SPM) and superconducting quantum interference device (SQUID) magnetometer. Cross-sectional TEM and magnetic force microscopy (MFM) results confirm the formation of nanocomposite. Magnetic characterizations reveal that nanocomposite exhibits ferromagnetic behavior with an increase in the coercivity, which is attributed to the formation of Ni nanoparticles. The coercivity of the nanocomposite is found to be 112 Oe at room temperature which is two orders of magnitude larger than that of the bulk Ni (0.87 Oe).

“…It may be due to the higher rate of electronic energy loss of 120 MeV Ni beams in polymer, which affects the optical properties of the polymer. It has also been observed that after irradiation, with subsquent evolution of hydrogen or other volatile components the sample become carbon rich 24. Kulshrestha et al25 irradiated PET with SHI and found that the shift of absorption edge was toward longer wavelength.…”

This experimental study investigated the modification of optical, structural and morphological properties of Makrofol‐KG and Polyethylene Terephtalate (PET) by irradiation of 120 MeV Ni+9 ions at fluences ranging from 1 × 1010 to 1 × 1012 ion/cm2. Optical and structural properties were studied by UV–visible spectroscopy and X‐ray diffraction (XRD) method, respectively. XRD studies of pristine and irradiated polymers revealed that crystallinity decreased after irradiation with swift heavy ions. The UV–visible spectrum displayed a shift in absorbance edge toward higher wavelength at higher fluence, which can be correlated with transition involved in polymers. Fourier transform infrared spectroscopy spectra were analyzed to investigate the changes in the chemical/structural properties of these polymers. The Makrofol‐KG is found to exhibit more pronounced modification compared to PET after irradiation by swift heavy ions. The surface morphology studied by atomic force microscopy showed that the roughness of polymers surface increased with increasing fluence. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
