Oxygen incorporation in polyethylene and polypropylene implanted with F+, As+ and I+ ions at high dose

Chemical aspects of implantation of high-energy ions into polymeric materials

“…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).…”

Modeling of displacement damage in an ion‐beam‐modified perfluorosulfonate ionomer

“…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…”

“…The use of a Monte Carlo simulation to model the effect of ion implantation into various polymers [e.g., polyethylene, polypropylene, poly(tetrafluoroethylene), and polyamide] has been demonstrated in the literature 23, 36, 37. The main purpose of these calculations is the estimation of the penetration depths.…”

Effect of ion beam irradiation on metal particle doped polymer composites

“…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.…”
