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
