Gamma- and Electron Beam-Induced Crystalline modification in Poly (Lactic Acid): Effects of Radiation Dose and Dose Rate
Abstract: Poly(lactic acid) (PLA) is an important commercial biodegradable polyester whose properties are dictated by its molecular architecture and semicrystalline nature. The application of ionizing radiation particularly gamma rays and electron beams is extensive for sterilization and materials processing. The effect of ionizing radiation on the crystallinity of PLA is complex however, since irradiation causes concurrently chain scission, radical formation, oxidation, recombination and mobility driven structural reorganization. This work studies the …
