摘要

摘要: 在聚合物共混物中或多种聚合物在同一空间并用时，各聚合物或聚合物组分的老化过程相互影响，即为聚合物老化传染行为。这种聚合物老化传染行为使针对单一品种聚合物老化的研究结果往往不能用以准确预测实际使用中聚合物材料的寿命，是老化研究领域的重要课题。本文综述了聚合物老化传染行为的研究进展，重点阐明老化传染行为的典型表现形式：“接触式”传播和“非接触式”传染，对传染媒介的来源和作用机制进行分析，介绍老化传染行为在环境保护和文物保护领域的应用，总结聚合物老化传染研究面临的挑战并展望前景。

Abstract: When polymers are in blends or used together, the ageing process of polymer components or polymers affects each other, which is called infection behavior of ageing. Due to the infection behavior during ageing of polymer, the research results of an individual polymer cannot be used to predict the life of this polymer material in blends or being used with other polymers. Therefore, infection behavior is an important topic in the field of ageing study. This article mainly features the research progress towards infection behavior of polymer ageing. Firstly, the "contacting" and "non-contacting" behaviors are emphatically illustrated, which are the two typical patterns of infection behavior of ageing. Ageing spreads via infection agents within a polymer or polymer blend, and between different polymers separated from each other. Infection agents play an important role in infection behavior. Then, the source and effects of infection agents are analyzed. Infection agents include radicals, volatile organic small molecules, gases, volatile additives and so on. All these infection agents work in "contacting" behavior, while volatile and gaseous matter are more important in "non-contacting" behavior. Benzoyl peroxide (BPO), formaldehyde and acetic acid are found to accelerate the thermo-oxidative ageing of polypropylene (PP). Eighteen volatile organic small molecules including acids, esters, aldehydes, ketones and alcohols are demonstrated to accelerate the photo-oxidative ageing of PP to different extents. Finally, the applications of infection behavior in the field of environmental protection and heritage protection are introduced and the challenges and prospects are proposed. The characterization of infection agents and their mechanism of action remain to be clarified systematically.
