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.

关键词: 二乙胺, 高硅, SAPO-34, 聚四氟乙烯, 复合材料

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 PTFE 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.

Key words: diethylamine, high-silica, SAPO-34, polytetrafluoroethylene, combined material
