Molecular Simulation of Functionalized Covalent Organic Framework Membranes for Inorganic Salt Separation

Advanced Theory and Simulations, EarlyView.
Six functionalized TpPa‐based covalent organic frameworks (COFs) are characterized using nonequilibrium molecular dynamics simulations to assess water permeance and salt rejection. The TpPa‐SO3H COF membrane achieves the highest sodium sulfate rejection (>98%) while maintaining relatively high water permeance compared to commercial nanofiltration ...
