摘　　要：将氧化钙（CaO）母料、稀土光敏剂和聚乙烯（PE）共混吹制成薄膜，通过人工加速老化、自然曝晒实验，采用FT—IR、TG-IR及SEM等分析手段进行表征。结果表明：CaO／PE可环境消纳薄膜具有明显的光降解性能，同时在焚烧处理时，可减少有害气体的产生量，具有热降解性能。Calcium oxide and rare earth metal photosensitive compound were used as fillers to prepare the environmentally degradable CaO/PE film. The film was subjected to artificially accelerated and natural exposure agings, and subsequently the environmental degradability was characterized using FTIR, TGIR, and SEM. It showed that the CaO/PE film had both photo- and thermal-degradability. In addition, the CaO/PE films discharged little poisonous gases when incinerated.
