摘要

采用机械球磨法快速合成了高活性的Zn-Fe双金属氰催化剂(DMC),继而在无溶剂的条件下催化氧化石墨烯(GO)、苯酐、CO₂和环氧丙烷(PO)原位聚合制备了GO/聚碳酸亚丙酯苯酐(GO/PPCPA)复合材料。通过红外光谱、扫描电镜和X射线衍射对催化剂的结构和微观形貌进行了表征,并采用热重分析研究了复合材料的热稳定性能。结果表明:4-二甲氨基吡啶(DMAP)和1-乙基-(3-二甲基氨基丙基)碳二亚胺盐酸盐(EDC)羧基活化剂对GO/PPCPA复合材料的热稳定性能有较大的影响,当GO/DMAP/EDC的质量比为1∶1∶1时,复合材料表现出最佳的热稳定性,失重为5%的热解温度(T_5%)、失重为50%的热解温度(T_50%)和最大分解温度(T_max)分别为118.8、349.3和361.6℃,相比PPCPA分别提高了23.7、54.1和49.5℃。

Abstract

Highly active Zn-Fe double metal cyanide catalyst (DMC) was rapidly synthesized by ball milling.Graphene oxide/poly (propylene carbonate phthalate)(GO/PPCPA) composite was synthesized by in-situ polymerization with graphene oxide (GO),phthalic anhydride,CO₂ and propylene oxide (PO) in the solvent-free.The structure and morphology of DMC were characterized by infrared (FT-IR),scanning electron microscopy (SEM) and X-ray diffraction (XRD).Additionally,the thermal stability property of GO/PPCPA was also evaluated by thermal gravimetric analysis (TGA).The results showed that DMAP and EDC as the carboxyl activators had the significant influence on the thermal stability of GO/PPCPA.When the mass ratio of GO/DMAP/EDC was 1∶1∶1,the composites exhibited the highest thermal stability.The mass loss temperature at 5%,50% and the maximum of decomposition rate were respectively 118.8,349.3 and 361.6℃,which increased 23.7,54.1and 49.5℃ in comparison with pure PPCPA.
