为了解决聚对苯二甲酸乙二醇酯(PET)材料制品使用后降解缓慢和聚2,5-呋喃二甲酸二甲酯(PEF)韧性差的问题,开发一种新型嵌段共聚酯聚2,5-呋喃二甲酸-乙二醇-co-对苯二甲酸酯(PEFT),可通过酯交换-熔融缩聚法合成,且PEFT拥有与PEF相媲美的热力学性能。利用FTIR及NMR等对聚酯结构进行表征,结果表明该方法成功制备了PEFT聚酯。通过TG、DSC和紫外光照表征,结果表明PEFT聚酯热学性能优良,且在紫外光照射下可快速降解。又将PEFT聚酯材料通过非溶剂致相分离法(NIPS)制备了不同铸膜液浓度的PEFT纳滤膜,用于对染料离子及金属盐溶液的截留,而后对其表面粗糙度、水接触角、荷电性、染料和金属盐离子的截留能力等方面进行了测试。结果表明:PEFT纳滤膜对甲基蓝(Mr=799.8)染料、酸性品红(Mr=585.4)染料都具有良好的截留性能,最高截留率可达99%和87.7%,并且纳滤膜经长期循环后仍具有较高的稳定性,但对金属盐(MgSO4)溶液截留性能不佳,截留率最高不超过35%。综合研究发现PEFT纳滤膜在染料截留方面性能突出。
