Effects of 3 MeV proton irradiation on the mechanical properties of polyimide films

6MeV pulsed electron beam induced surface and structural changes in polyimide

“…For e.g., the effects of 3 MeV proton radiation on the mechanical properties [7], 2 MeV electron irradiation on spectroscopic and thermal properties [8], 2 MeV electron radiation on mechanical properties [9] and 4 MeV light ions on hardness and Young's modulus [10] of various polyimides are reported. However, more investigations are needed as far as the radiation energy, mode of energy deposition and energy densities are concerned.…”

“…This material is used in diversified areas such as space missions, nuclear, electronic and automotive industry, where its applications mainly include shielding material and reflective films for thermal and radiation control and insulating material in electronic circuits and components [6,7].…”

Proton-Radiation Tolerance of Silicon and SU-8 as Structural Materials for High-Reliability MEMS

“…LET-dependent radiation effects, in which the observed damage is correlated to the electronic stopping power of the radiation, were investigated in various polymers including aromatic and aliphatic compounds [23], [25], [27], solid alanine [28], polystyrene, and polysilanes [29], [30]. However, [31] reported similar effects on the elongation to break in Ultem and Kapton irradiated by 3 MeV protons, 2 MeV electrons, or gamma-rays. Thresholds for the appearance of LET effects were also reported.…”

A comparative study on the effects of Co-60 gamma radiation on polypropylene and polyimide

“…These techniques not only facilitate in understanding the fundamental radiation physics and chemistry of polymers, but also provide information required for designing radiation stable polymeric systems such as blends and composites, radiation processing of polymers, radiation-enhanced diffusion, tailoring the properties and radiation-assisted synthesis of polymer nanocomposites. This requires a comprehensive and thorough understanding of effects of various particulate as well as non-particulate radiations on both radiation-resistant as well as radiation-sensitive polymers (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11).…”
