FABRICATION AND MICROSTRUCTURES OF POROUS ALUMINA WITH POROUS-AND-DENSER ZEBRA-PATTERNED SURFACES CREATED BY ONE-POT DIRECT BLOWING METHOD

摘要

Porous-and-denser zebra-patterned surface was fabricated on porous alumina by a direct blowing route and controlling the evolution. In addition to the porous-and-denser zebra-patterned surface, other two types of surface structures, including a porous surface structure and denser surface structure were prepared in order to discuss the effects of those surface structures on air permeability.
