摘要
本文研究了不同厂家背板湿热老化前后的力学性能、PET层结晶度以及红外吸收峰的变化,得出了背板失效与其PET层结晶度的关系。
In this paper, mechanical properties, crystallinity of PET layer and infrared absorption peak of backsheets from different factories are studied following the changes before and after hydrothermal aging, and relationship between failure of backsheets and crystallinity of PET layer is concluded.
