摘要
本文综述了研究团队利用γ射线辐照技术在聚烯烃体系辐射交联，以及填充橡胶体系制备与设计中的应用。重点介绍团队如何利用同步辐射光源和中子散射技术对两种材料体系进行原位研究，以深入理解材料的微观结构和性能关系。首先展示通过γ射线辐照技术引发高分子链间的化学反应，促进新化学键的形成，进而设计和调控所需材料体系。团队以此为基础利用国内大科学装置开展原位研究。这些工作不仅展示了我国包括三大中子源、同步辐射光源在内的大科学装置建设方面的成就，也体现了装置在促进各领域，尤其是在高分子基材料的微观结构和动态过程研究中的独特优势。
Abstract
This review article highlights our group's use of γ-irradiation for crosslinking polyolefin systems and designing filled rubber systems. It emphasizes the application of synchrotron radiation and neutron scattering techniques for in situ studies on both material systems
providing an in-depth understanding of the relationship between the microstructure and properties of the materials. The article first illustrates how γ-ray irradiation initiates chemical reactions between polymer chains
promoting the formation of new chemical bonds to design and control the desired material systems. Based on this
our group has conducted in situ studies using major scientific facilities in China. These efforts not only showcase the advancements in the construction of major scientific facilities in China
including the three major neutron sources and synchrotron radiation sources
but also demonstrate the unique advantages of these facilities in promoting various fields
particularly in exploring the microstructure and dynamic processes of polymer-based materials.
