This paper provides new insights for the study of polymer degradation through the detection of markers released at the polymer surface using Al-coated SERS active substrates. Combining a nanodestructive sampling procedure with the SERS sensitivity allows achieving detection limits much lower than traditional polymer characterization techniques, opening the way to the use of SERS as part of an innovative strategy to diagnose surface degradation in polymeric museum artefacts. The method was applied to artificially photo-aged model polymers and to museum artworks.

通过基于SERS的新策略检测聚合物表面的降解标记

本文通过使用涂有Al的SERS活性底物检测聚合物表面释放的标志物，为研究聚合物降解提供了新的见解。将纳米破坏性采样程序与SERS灵敏度相结合，可以实现比传统聚合物表征技术低得多的检测极限，从而为使用SERS作为诊断聚合物博物馆文物表面退化的创新策略的一部分开辟了道路。该方法被应用于人工光老化的模型聚合物和博物馆艺术品。
