Preparation of Perfective TAPO-5 Membrane through Tertiary Growth with Amorphous Seed

TAPO-5 membranes were synthesized through a tertiary growth method. Its perfection significantly depends on the adopted seed and itself poly-crystalline structure. Amorphous seed synthesized at a low crystallization temperature (393 K), obviously favors producing the perfective TAPO-5 membrane. TAPO-5 crystal seed, however, induces the growth of its membrane with a larger extent of cracks (i.e., grain boundary defect), destructing itself perfection.
