“…For both aliphatic and aromatic polymers irradiated by ions with medium energies (hundreds of kiloelectron-volts) carbonisation of their surfaces nearly goes to completion at implantation doses of 5610 15 to 10 16 cm 72 and subsequent ion bombardment causes only slight changes in the composition of the implanted layer. 35,36 Noteworthy is that no full carbonisation of the polymer surface occurs. For instance, implantation of polyethylene with 150 keV F + ions (S e /S n & 5) leads to an increase in the concentration of carbon in the implanted layer from 33% (in the pristine polymer) to 40%.…”

“…For instance, implantation of polyethylene with 150 keV F + ions (S e /S n & 5) leads to an increase in the concentration of carbon in the implanted layer from 33% (in the pristine polymer) to 40%. 35 The extent of dehydrogenation of ion irradiated polymers rapidly increases with increasing energy transferred from the incident ions by nuclear collisions. In particular, saturation of carbon concentration in the implanted layer is reached at 65% for implantation of polyethylene with 150 keV As + ions (S e /S n & 0.3).…”

“…The main purpose of these calculations is the estimation of the penetration depths. The results from applications of the TRIM (Transport and Range of Ions in Matter) program38, 39 show nearly quantitative agreement with implant profiles measured by the Rutherford backscattering technique 23, 36, 37…”

A Monte Carlo simulation has been used to model the effects of mediumenergy ion-beam modification of Nafion. With typical ion energies of 100 -200 keV, the treatment affects the outer 0.5-2-m surface layer. An equation has been developed for predicting the expected range of implantation as a function of the ion energy and atomic number. The expected range of displacement damage due to the ion beam can similarly be described over the whole parameter range of interest with a double logarithmic fit. A full characterization of the distributions with their first four statistical moments is also presented. The quantitative description of the profiles obtained is useful for the rational design of an ion-beam treatment for the preparation of integrally skinned membranes.

“…Thus, optical, mechanical, electrical and chemical properties can be selectively modified using ion beam bombardment (Solfield et al 1993;Vacik et al 1997). Ion irradiation of polymer is followed by the processes of macromolecular distribution, cross-linking, free radicals formation, carbonization and oxidation (Bedell et al 1990;Hnatowicz et al 1994). Therefore, understanding of certain structural rearrangements of the polymer composites opens a way to design devices with required parameters.…”

Polymethyl methacrylate (PMMA) was prepared by solution polymerization method. Different concentrations (10, 20 and 40%) of Ni powder were dispersed in PMMA and the composite films were prepared by casting method. These films were irradiated with 120 MeV Ni 10+ ions at a fluence of 5 × 10 12 ions/cm 2 . Electrical, structural and chemical properties of the composites were studied by means of an LCR meter, X-ray diffraction, FTIR spectroscopy and SEM/AFM, respectively. The results showed that the conductivity increases with metal concentration and also with ion beam irradiation. This reveals that ion beam irradiation promotes the metal/polymer bonding and converts polymeric structure into hydrogen depleted carbon network. It was observed from XRD analysis that percentage crystallinity and crystalline size decrease upon irradiation. This might be attributed to rupture of some polymeric bonds, which is also corroborated with FTIR spectroscopic analysis. Ion beam tempts graphitization of polymeric material by emission of hydrogen and/or other volatile gases. Surface morphology of the pristine and irradiated films was studied by atomic force microscopy (AFM)/scanning electron microscopy (SEM). Result showed that the surface roughness increases after ion beam irradiation.
