Nanoporous alumina is a ceramic material fabricated by anodic oxidation of pure aluminum. The material can be used directly as transparent, opaque or white membrane (depending on the pore diameter) or as a one-side-closed template for the formation of nanostructures. The product is an amorphous oxide which can be changed to a crystalline structure by heat treatment. The pore diameter can be adjusted with a precision on nanometer scale.

It exhibits a homogeneous morphology of parallel pores which grow perpendicular to the surface with a narrow distribution of diameters and interpore spacings, with a standard deviation of maximum 10% in the nanometer scale.

Because of the above mentioned unique properties, nano porous alumina can be used in a wide range of applications, such as filters, as platforms for multi-functional flow-through sensors, as nano reactors, and especially as templates for the fabrication of nanometer-scale composites, such as nanotubes or nanowires by electrochemical deposition or by using polymer melts.

The SmartPor membranes offer high-ordered round pores with an unique pore diameter (deviation lower 10%) which stays constant through the complete length of the pores. The pores are arranged triagonally with a self-order within the crystal mono domains of the alumina.
