Gamma-induced modifications of polycarbonate polymer

Dose-Dependent Effects of Gamma Irradiation on the Materials Properties and Cell Proliferation of Electrospun Polycaprolactone Tissue Engineering Scaffolds

“…These results reflect that the amorphous character of the polymer decreases and crystallinity increases with increase in dose, which may be due to the scissioning of the polymer chains, by which the polymer undergoes some spatial rearrangement [21]. The small fragments may rearrange themselves towards new crystalline zone.…”

The physical and chemical properties of gamma ray irradiated polymer electrolyte films

“…The gamma irradiation has been found to have the ability to expose the whole area of the sample and expected to create homogeneous modifications in the sample. The gamma irradiation treatment provides a unique way to modify the physical and chemical properties of the polymer electrolytes by causing irreversible changes in their macromolecular structure [19][20][21][22]. By controlling the experimental conditions (monomer concentrations, radiation dose rates, and irradiation environments) one can tailor the final properties of the materials in order to produce new materials for specific application.…”

Polycarbonate/TiO2 nanofibers nanocomposite: Preparation and properties

“…However, the exposure of polycarbonate to radiation causes its yellowing, mainly due to photo‐oxidation of aromatic rings and chain scission degradation of the carbonyl groups on PC molecular structure . In consequence, the polymer begins to show a decreasing of mechanical properties and aesthetic integrity .…”
