Porous templates can be fabricated using several methods. Some of the most common techniques include:
Anodic Aluminum Oxide (AAO): This technique involves the electrochemical oxidation of aluminum in an acidic electrolyte to form a porous aluminum oxide film. Track-Etched Membranes: These membranes are created by bombarding a polymer film with high-energy particles, followed by chemical etching to form uniform pores. Self-Assembled Block Copolymers: These copolymers can spontaneously form periodic nanostructures, which can be used as templates for further processing.
