摘要
聚合物的老化行为及防老化研究是聚合物材料的基础科学问题和热点领域之一。本文详细介绍了聚合物材料常见的热氧老化和光氧老化的过程和机理、防老化原理和方法、各种抗老化助剂的种类以及评价方法等,重点介绍了本课题组近几年来使用纳米粒子作为抗老化助剂的研究成果,主要包括纳米二氧化硅、纳米二氧化钛和纳米氧化锌等。
The environmental stability, including ageing behaviors and anti-ageing, of polymers is an important basic science topic and has become a research hotspot in recent years. This paper introduced the processes and mechanisms of thermal oxidation ageing and photo-oxidation ageing of polymers. The characterization methods and the anti-ageing additives were introduced too. Nanoparticles, such as nano-silica, nano-titanium dioxide and nano-zinc oxide, are today considered new-generation anti-ageing agents with enhanced performance. Some achievements obtained by us in the field were reviewed here.
