Microstrain analysis of proton irradiated PET microfiber

Effect of gamma irradiation on the properties of plastic bottle sheet

“…As expected, gamma irradiation leads to deformation of polymer structure. Not only this, we have observed significant decrease in diffraction peaks broadening [25]. It is well documented in literature that decreased in peak intensity of diffraction peaks is usually related with the decrease in crystallinity, and the broadening of the peak is associated with the decrease in average crystallite size [26][27][28].…”

“…This observed change in diffraction peaks intensity may be due to the destruction of the original structure of the plastic bottle [24]. The overall increases in peak intensity suggest a convergence of plastic sheets towards more ordered arrangement after gamma irradiation [25]. As expected, gamma irradiation leads to deformation of polymer structure.…”

“…It is clear from the figure that the overall area increases after irradiation, resulting in the enhancement of crystallinity thereby leading to the more ordered structure. Furthermore, the crystallite size (L), interchain separation (R), interplanar distance (d), micro strain (e), dislocation density (d) and distortion parameters (g) were calculated as follows [25,34,35]:…”

Degradation of nickel (86MeV) ion irradiated polystyrene

“…Minimum value of d 1 is seen for the fluence of 1 · 10 11 ions cm À2 . This result is well supported by the earlier reported results on proton irradiated PET fibers [9]. It is also observed from Table 2 that position of second diffraction peak shifts towards higher angle with the increase of 58 Ni 7+ (86 MeV) ion fluence, which may be due to the decrease of interplanar spacing, d 2 .…”

Modification of Optical and Electrical Properties of PET Foils by He+, Ne^+ and Ar^+ Implantation

“…It is a very popular polymer used widely for packaging purposes as well as fiber production [14,15] but also for light fibre photographic filters and lens production etc. [16]. Numerous studies of PET samples irradiated by noble gases [17][18][19][20][21][22], metals [23][24][25] and nonmetals [2,26] were reported.…”
