Ion beam modification of polymers

Effect of ion beam irradiation on metal particle doped polymer composites

“…The growing interest in the ion beam irradiation of polymeric material is due to possibility of verification of the technological parameters as the fundamental reason and also considering some possible applications to device fabrication. 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).…”

Modification of Chitosan Membranes via Methane Ion Beam

“…Yu and his colleagues [12] have shown that chitosan membranes after modification by ion beams represented the cell membrane mechanism during the transferring of genes. Researchers have been exploring the modification of polymers by plasmas, lasers, UV lamps, electron beams, ion beams, and gamma rays [13][14][15][16][17][18][19][20][21]. The ion beam implantation technique is a well-known and effective method to modify polymers [22,23].…”

Changes in Structural and Optical Properties of Polycarbonate Induced by Ag+Ion Implantation

“…The alteration of the polymeric properties is both due to the presence of the implanted impurities, which change the polymer composition, and due to the irradiation-induced effects initiated by them, which alter both the chemical composition and the structure of a polymer by causing chain scission, cross-linking, free radical formation, dangling pair production, etc. [14][15][16] Polycarbonate (PC) is widely used in optical applications due to its combination of chemical stability and optical and mechanical properties. It is a potential material for fabrication of optical sensors, light emitting diodes, integrated optics for communication and signal processing, antireflective coatings, etc.…”
