Communication-Fabrication of Hydrophobic, Nanoporous, Anodic Alumina by Adjusting Surface Morphology
We describe the fabrication of hydrophobic, nanoporous, anodic alumina (NAA) by controlling its surface morphology, without chemical modification. Micro-roughness and large nanopores increase the water contact angle of the surface. Sandblasted NAA (SNAA) was fabricated by anodizing after sandblasting the aluminum surface. Water contact angles on the surfaces of SNAA and of NAA chemically modified with a hydrophobic chemical differ very little. (C) 2017 The Electrochemical Society. All rights reserved.
