Orientation on Periodical Micro Pattern with Vertical and Homogeneous Alignments Using Anodic Porous Alumina for Bi-Stable Surface
In order to obtain the bistable surface, a new method is proposed to fabricate the micro-patterned substrate surface formed by stripes of alternating vertical and planer anchorings. In this method, aluminum film evaporated in vacuum on substrate surfaces was etched in stripe pattern using the photolithography techniques. And then, stripes of aluminum were anodized. Coexistence of the vertical alignment on stripes of porous alumina and the planer alignment along stripes due to grooves between stripes of alumina is experimentally confirmed. However, the bistable property has not been observed yet.
