“…From Fig. 10, it can be inferred that the Urbach energy of the implanted CR-39 is increased with the ion fluence due to high concentration of disordered carbon content [6]. These carbonaceous clusters are supposed to be the main absorbing centers in the specimen.…”

Ion implantation has a potential to modify the surface properties and to produce thin conductive layers in insulating polymers. For this purpose, poly-allyl-diglycol-carbonate (CR-39) was implanted by 400 keV Au + ions with ion fluences ranging from 5 × 10 13 ions/cm 2 to 5 × 10 15 ions/cm 2 . The chemical, morphological and optical properties of implanted CR-39 were analyzed using Raman, Fourier transform infrared (FT-IR) spectroscopy, atomic force microscopy (AFM) and UV-Vis spectroscopy. The electrical conductivity of implanted samples was determined through four-point probe technique. Raman spectroscopy revealed the formation of carbonaceous structures in the implanted layer of CR-39. From FT-IR spectroscopy analysis, changes in functional groups of CR-39 after ion implantation were observed. AFM studies revealed that morphology and surface roughness of implanted samples depend on the fluence of Au ions. The optical band gap of implanted samples decreased from 3.15 eV (for pristine) to 1.05 eV (for sample implanted at 5 × 10 15 ions/cm 2 ). The electrical conductivity was observed to increase with the ion fluence. It is suggested that due to an increase in ion fluence, the carbonaceous structures formed in the implanted region are responsible for the increase in electrical conductivity.

“…The present study confirmed that the E g -value for the virgin sample was reduced due to alpha particle irradiations. The variations in E g suggest formation of defects (radicals and organic species) after alpha particles irradiations and/or the formation of carbon enrich clusters [22]. This may be attributed to the formation of a conjugated system of bonds due to bond cleavage by radiation.…”

“…13,14 Several studies have shown that irradiation of polymers with swift heavy ions (SHI) leads to a wide variety of changes in properties. [15][16][17][18][19] Guenther et al 20 irradiated PES by boron ions and found that density and electrical conductivity of the polymers layers are enhanced with increasing boron energy and dose. Similar work also has been carried out on the interaction of heavy ions with polymers and other materials by several workers.…”

High-energy ion beam irradiation of polymer is an effective technique to enhance the optical, structural, and mechanical properties. So polyether sulfone (PES) films were irradiated by lithium ions (energy 45 MeV, charge state 3+) and nickel ions (energy 120 MeV, charge state 9+) with fluence varying from 3 × 10 10 to 3 × 10 12 ions/cm 2 . Ion-induced optical, structural, and surface modifications were studied by ultraviolet-visible (UV-Vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffractrometer (XRD), and atomic force microscopy (AFM). PES suffers degradation under irradiation. It is observed that the band gap of the polymer decreases with ion fluence. The decrease in the band gap was found to be more in the case of the Ni ion beam as compared to the Li ion beam. The intensity of the infrared bands, characteristics of different chemical functional groups are found to be decreased with swift heavy ion (SHI) irradiation. Significant loss of crystallinity was observed at higher fluences. Atomic force microscopy showed that the roughness of the polymer surface increased with increasing fluence C
