Producing zeolite films with controlled preferred orientation on an industrial scale is a long-standing challenge. Herein we report on a scalable approach to the direct wet deposition of zeolite thin films and membranes while maintaining a high degree of control over the preferred crystal orientation. As a proof of concept, thin films comprising aluminophosphate zeolite AEI were cast on silicon wafer or porous alumina substrates. Electrical properties and separation performance of the zeolite thin films/membranes were engineered through controlling degree of preferred crystal orientation.
在工业规模上生产具有可控择优取向的沸石膜是一个长期存在的挑战。在此，我们报告了一种可扩展的方法，用于直接湿法沉积沸石薄膜和膜，同时保持对择优晶体取向的高度控制。作为概念验证，将包含磷酸铝沸石AEI的薄膜浇铸在硅片或多孔氧化铝基板上。通过控制择优晶体取向程度来设计沸石薄膜/膜的电学性能和分离性能。
