摘要:
针对乙二醇醇解废弃聚酯存在解聚效率低、催化剂回收难的问题 , 以化学稳定性好的碳纤维为载体 ,通过沉积聚多巴胺改性碳纤维 ,并采用化学法将氧化锌负载到聚多巴胺改性的碳纤维上 ,制备聚多巴胺改性碳纤维负载氧化锌催化剂(ZnO@CFs-PDA) ;采用扫描电子显微镜、透射电子显微镜、X射线光电子能谱等对 ZnO@CFs-PDA进行结构表征 ,并评估 ZnO@CFs-PDA解聚废弃聚酯的性能 。结果表明 :碳纤维上成功负载了氧化锌颗粒 ;在最佳醇解反应条件下 ,聚对苯二 甲酸乙二醇酯(Polyethylene terephthalate, PET)转化率为 100% ,对苯二 甲酸双羟乙酯(Bis-2-hydroxyethylterephthalate, BHET)产率为 72.6%;ZnO@CFs-PDA 经过 5 次循环后 ,PET转化率和 BHET产率分别为 85.5%和 52.1% 。该研究制备的 ZnO@CFs-PDA对废弃聚酯具有良好的解聚性能及重复使用性 ,为废弃聚酯高效解聚及绿色催化剂的开发提供了新思路。
