When an energetic ion traverses a polymer medium, it loses its energy by electronic and
nuclear processes. In the past, considerable research efforts have been devoted to …

Mechanisms of scission and cross-linking are investigated for poly (methyl methacrylate)
subjected to various irradiation sources, such as low LET radiation sources (MeV e-beams …

A major challenge in nanofabrication is to pattern unconventional substrates that cannot be
processed for a variety of reasons, such as incompatibility with spin coating, electron beam …

The formation of carbonaceous clusters in swift heavy ion irradiated polymer films has been
investigated extensively. The information about these clusters may be obtained from …

Abstract Polymer electrolyte (PEO: Li 2 SO 4) films were exposed to 8 MeV electron beam
(EB) with various doses to investigate the radiation effect on dielectric permittivity (real and …

Ion bombardment is a suitable tool to improve the physical properties of polymers. In the
present study, the effect of ion bombardment on the optical properties of low density …

Nitrocellulose films have been shown to function as self-developing resist layers that are
sensitive to both low-energy (< 2 ke V) Ar+ ions and to 193-nm UV radiation from pulsed …

Poly (methyl methacrylate)(PMMA), known as a radiation-degrading polymer, showed
mechanically hardening behavior under a high-fluence electron irradiation. When the …

Ion bombardment is a suitable tool to improve the physical and chemical properties of
polymer surface. In this study UHMWPE samples were bombarded with 130keV He ions to …

The effects of swift heavy ions and gamma radiations upon the nano-scale free volume of
the polymethylemethacrylate (PMMA) polymer were investigated using positron annihilation …
