Abstract

To address the challenges associated with significant mechanism discrepancies and ambiguous application scenarios of high-energy radiation technologies in polymer modification, the work aims to elucidate the distinctions among five mainstream techniques: electron beam (EB), gamma-ray, X-ray, ultraviolet (UV), and plasma, so as to provide a theoretical basis for precise material modification and optimal process selection. Based on a systematic review of domestic and international literature from the past decade, core mechanisms, including radiation crosslinking, grafting, curing, and degradation, starting from the principles of radiation energy transfer were elaborated. A comparative analysis is conducted regarding the penetration depth, modification efficiency, and equipment costs of the five techniques. Furthermore, their progress in applications such as mechanical reinforcement, barrier property improvement, and biocompatibility regulation is summarized. Finally, it is proposed that future research should focus on multi-technology synergistic effects (e.g., radiation-chemical coupling), precise control of the modification process, and the development of low-cost industrial equipment to expand its depth of application in high-value-added fields.
