Swift Heavy Ion (SHI) irradiation was carried out in vacuum at the Pelletron facility of Nuclear Science Centre, New Delhi, India using ion beam fluences of 3.0×10<sup>11</sup>, 3.7×10<sup>12</sup>, 1.8×10<sup>13</sup> and 5.6×10<sup>13</sup> and 1.2×10<sup>14</sup> ions/cm<sup>2</sup>. UV-Visible spectra reveal both chain-scission and cross-linking of PET. FTIR spectra show a significant loss of crystallinity at low radiation doses but recovery of pristine structure at a fluence of 5.6×10<sup>13</sup> ions/cm<sup>2</sup>. Both UV-Visible and FTIR spectra support the conclusion that molecular reorientation of PET leading to recovery of original structure is affected at high irradiation dose of carbon ions. XRD spectra for both virgin and irradiated PET also confirm this conclusion. </smarttagtype></smarttagtype></smarttagtype> |
