Nanomembranes - Nanotechnology

What are Nanomembranes?

Nanomembranes are ultra-thin, flexible membranes engineered at the nanoscale. They possess unique mechanical, chemical, and physical properties that make them highly desirable for various applications. Typically, nanomembranes are only a few nanometers to a few micrometers thick, making them significantly thinner than conventional membranes.

How are Nanomembranes Fabricated?

The fabrication of nanomembranes involves advanced nanofabrication techniques such as atomic layer deposition (ALD), chemical vapor deposition (CVD), and electrospinning. These techniques allow for precise control over thickness, composition, and surface properties. Additionally, methods like self-assembly and layer-by-layer assembly are used to create complex nanomembrane structures.

What are the Key Properties of Nanomembranes?

Nanomembranes exhibit several exceptional properties, including high surface area-to-volume ratio, tunable porosity, mechanical strength, and chemical robustness. Their flexibility allows them to conform to various shapes and surfaces, making them ideal for flexible electronics and wearable devices. Their ability to filter specific molecules with high precision makes them suitable for water purification and gas separation.
