摘要
双酚A型聚碳酸酯性能优异,应用广泛。但在户外使用时,由于光、氧和湿度等环境因素的作用,导致聚碳酸酯力学强度和外观发生变化。为提高PC的抗老化性能,必须通过研究,充分认识聚碳酸酯的老化反应和老化进程。综述了近年来聚碳酸酯老化行为的研究,并提出存在的问题和今后研究的方向。
Bisphenol a polycarbonate （PC） is one of the most widely used engineering thermoplastic owing to excellent physical and chemical properties. When bisphenol a polycarbonate is used in outdoor applications, it starts to show losses ＆ mechanical properties due to sunlight, humidity and oxygen. To increase its lifetime, this undesirable degradation process needs to be, overcome. Therefore, it is necessary to know what chemical degradation reactions occur and how these processes are initiated. This review briefly summarized the new research of ageing behavior of polycarbonate, along with the existing problems and developing trend.
