摘要
主要研究了热老化对PMMA塑料光纤损耗的影响及其影响机理。发现热物理老化减少了PMMA聚合物中的局部取向,使其形成少量的半结晶或结晶区,增加了其散射损耗;而热化学老化导致PMMA聚合物的氧化降解,严重增加了其在短波长的电子转移吸收损耗。
The influence and influence mechanism of heat aging on the attenuation of PMMA polymer optical fiber (POF) were studied. It was found that scatter loss of POF increased because of the heat-physical-aging, which could reduce the local tropism of polymethyl methacrylate (PMMA) polymer and then a few half-crystal or crystal zone formed; the electron-transfer absorption loss of POF was observably increased because of the heat chemical aging, which led to PMMA polymer oxygenation decomposing.
