摘要

研究表明，高能电子照射聚醚砜会改变其稳态和时间分辨荧光的行为。这主要是由于材料内部发生的交联程度，尽管人们认识到在一定程度上也会发生链断裂。因此，荧光被证明是监测聚合物结构变化的一种可行的技术。

The influence of high-energy electron radiation on the distribution of fluorescence lifetimes in polyethersulphone

The authors show that high-energy electron irradiation of polyethersulphone brings about changes in the behaviour of both its steady-state and time-resolved fluorescence. This is due largely to the degree of crosslinking that takes place within the material, although it is recognised that chain scission also occurs to a certain extent. Thus, fluorescence is demonstrated to be a viable technique for monitoring structural changes in polymers.
