Full Form: Anodic Alumina Membrane
For more information of "Anodic Alumina Membrane", see the section below.
### What is AAM?
AAM is a thin, self-ordered, and highly porous oxide layer formed on the surface of aluminum metal by electrochemical anodization. The anodization process involves immersing the aluminum in an electrolyte solution and applying a voltage. This process leads to the formation of a porous alumina layer with a uniform pore size and a high aspect ratio.
### Properties of AAM:
- High porosity: AAM membranes have a porosity of up to 95%, allowing for high flow rates.
- Uniform pore size: The pores in AAM membranes are highly uniform in size and shape, providing precise control over filtration and separation.
- Chemical stability: AAM is chemically inert and resistant to harsh chemicals, making it suitable for a wide range of applications.
- Mechanical strength: AAM is a mechanically strong material, making it durable and resistant to deformation.
### Applications of AAM:
AAM is used in various applications, including:
- Filtration: AAM membranes are used in water purification, wastewater treatment, and gas filtration.
- Separation: AAM membranes can be used to separate particles, molecules, and ions based on their size and charge.
- Catalysis: AAM membranes can be coated with catalytic materials, making them useful for reactions like water splitting and hydrogen production.
- Sensors: AAM membranes can be integrated with sensors to detect ions, molecules, and biomolecules.
