“…It is already an established fact that the interaction of radiation with polymers leads to chain scission and formation of double bonds. As ar esult, the properties of the polymer are modified (Nouh and Bahmmam, 2012;Sinha et al, 1998;Phukan et al, 1999). For proton irradiated polycarbonates, registration sensitivity increases with proton energy, reaching amaximum at about 0.5 -0.8 MeV (Darraud-Taupiac et al 1997).…”

Light diffusing polycarbonate samples were exposed to protons fluences at levels between 10 11 and 10 16 p/cm 2 .T he variation of the refractive index and color intensity with the proton fluence has been studied. The results show that the polycarbonate samples acquire color changes under proton irradiation. Furthermore, thermogravimetric analysis has been performed. It was found that both the onset temperature and activation energy of thermal decomposition are affected by the proton fluencies owing to the degradation and crosslinking processes. Moreover, structural property studies using X-ray diffraction, intrinsic viscosity and Fourier transform infrared spectroscopy were performed.

“…1 At the same time, radiation modification of polymers is one of the methods that enable the receiving of new polymeric materials with specific properties. [4][5][6][7] The obtained chemical system is characterized by new functional groups, a different backbone with different electronic structure and different physical properties. 3 It is already an established fact that the irradiation of polymers leads to chain scission, chain aggregation, and the formation of double bonds; thus the properties of the polymer are modified.…”

Makrofol BL 2-4 is an extrusion film based on Makrolon polycarbonate. It is different from Makrofol DE as it comprises excellent die-cutting performance combined with high light transmission and moderate light scattering properties. It is a polymeric solid-state nuclear track detector, which has many applications in various radiation detection fields. Samples from Makrofol BL sheets were irradiated using different electron beam doses ranging from 20 to 300 kGy. It is worth mentioning that this report is almost the first one dealing with this topic of material changes using Makrofol BL 2-4. The resultant effect of electron beam irradiation on the properties of Makrofol has been investigated using X-ray diffraction, intrinsic viscosity, Fourier transform infrared spectroscopy, thermogravimetric analysis, refractive index, and color difference studies. The results indicate that the electron beam irradiation in the dose range 50-200 kGy led to the dominance of cross-linking, enhancing the properties of Makrofol. C 2015 Wiley Periodicals, Inc.

“…It is already an established fact that the interaction of radiation with polymers leads to chain scission, chain aggregation, formation of double bonds and molecular emission. As a consequence of this, the optical and structural properties of the polymer are modified (8)(9)(10)(11)(12)(13). In addition, electron beam irradiation can * be considered as one the most popular and well-established processes for several applications.…”

The effect of electron beam irradiation on the structure and optical properties of a PM-355 solid-state nuclear track detector has been investigated. Samples from PM-355 were irradiated with electron beams with different doses ranging from 20 to 250 kGy. The structural and optical modifications in the electron beam-irradiated PM-355 samples have been studied as a function of dose using different characterization techniques such as Fourier transform infrared spectroscopy, Vickers hardness, refractive index and color difference measurements. The Commission International de E'Claire (CIE units x, y and z) methodology was used in this work for the description of colored samples. In addition, the color differences between the non-irradiated sample and those irradiated with different electron beam doses were calculated. The results indicate that the PM-355 detector acquires color changes under electron beam irradiation.
