摘　　要：以二乙胺为结构导向剂,在聚四氟乙烯乳液中水热法合成了高硅SAPO-34与聚四氟乙烯复合材料.XRD表明合成样品为SAPO-34结构,SEM照片表明型貌完好,周围牢固地覆盖着聚四氟乙烯材料.与不加聚四氟乙烯乳液合成样品相比,添加后晶粒尺寸增大,晶型更完好,疏水和成膜性能提高.In this paper, combined material of high-silica SAPO-34 with polytetrafluoroethylene （PTFE） was hydrothermally synthesized with diethylamine as the structure-director. It is indicated that the synthesized sample possesses SAPO-34 structure from XRD spectrum and perfect shape surrounded firmly by FIFE material from SEM images. Compared with sample synthesized without PTFE, SAPO-34 in the combined material is much larger in size and perfect in shape. And its hydrophobic and flexible membranous properties have been enhanced.
