“…up to 5 · 10 12 ions cm À2 ), which may be attributed to increase of ordering in some micro-domains within this range of ion fluence. At the fluence of 1 · 10 13 ions cm À2 , there is increase of Urbach's energy, which might be due 0.0 2.0x10 12 4.0x10 12 6.0x10 12 8.0x10 12 1. to overall degradation of the polymer. A very good corroboration between Urbach's energy and FWHM of second X-ray diffraction peak is evident from Fig.…”

“…A decrease in the melting temperature in irradiated samples would indicate significant depolymerization as observed, for example by Liu et al(2000) [51] in particle irradiated PET samples. In our PET and its nanocomposites the maximum peak temperature of melting did not change significantly probably because of lower linear energy transfer (LET) of protons compared to the ions Liu et al (2000) [51] used.…”

“…We have chosen polymethylmethacrylate (PMMA) polymer for our present investigation because of its wide range of utilization such as it is finding extensive use in expanding optical networks in the field of telecommunication. Previous studies [14,15] have been undertaken by inert ion irradiation of higher energies. It was thought worth while to study and compare the results of 0168-583X/$ -see front matter Ó 2011 Elsevier B.V. All rights reserved.…”
