Abstract
Methods of forming porous media (e.g., membranes for liquid separations or parts thereof) via polymerization, and related articles, are generally described. In some instances, two components are combined such that a polymerization (e.g., interfacial polymerization) reaction occurs, resulting in the formation of polymer layer (e.g., an active layer). In some instances, the two components include a first solution including water and a relatively low concentration of a first monomer (e.g., an amine-containing monomer such as optionally-substituted m-phenylenediamine) and a second solution including a nonpolar organic liquid and a relatively low concentration of a second monomer (e.g., an acid halide-containing monomer such as an optionally-substituted trimesoyl chloride).
