Abstract
In this study, we developed an evaporation-driven self-assembly coating method for an ceramic intermediate layer on an ultrapermeable ��-Al2O3 support with large pore size of ~1.5 ㎛. The method led to the formation of a ceramic intermediate layer with higher surface homogeneity and less surface roughness than the conventional dip-coating method. A mesoporous ��-Al2O3 layer was deposited on the support to evaluate support quality. A supported ��-Al2O3 membrane was defect-free even without repeated coating. Furthermore, the membrane showed 2.3 times higher nitrogen permeance than one prepared on a macroporous support with pore size range of 100~200 nm, which is widely used for ceramic membrane coating.
