Janus Membranes via Atomic Layer Deposition (ANL-IN-17-134)

A membrane exhibiting sides with different properties

A membrane exhibiting sides with different properties (“Janus membrane”) and methods of fabricating such a membrane. The membrane comprises a polymer material lacking polar functional groups. One side of the membrane is masked during atomic layer deposition (ALD). ALD is utilized to deposit a conformal coating on an exposed side of the membrane. More
