Thickness-Dependent Permeability of Molecular Layer-By-Layer Polyamide Membranes

August 28, 2020
Author(s)
William D. Mulhearn, Vladimir Oleshko, Christopher Stafford
We present the thickness-dependent permeability of highly crosslinked polyamide (PA) membranes formed by a molecular layer-by-layer (mLbL) deposition process. The deposition allows for the synthesis of extremely smooth, uniform PA films of tunable

Reverse osmosis using aromatic polyamide membranes is currently the most important technology for seawater desalination. The performance of reverse osmosis membranes is highly dependent on the interplay of their surface chemical groups with water and water
