Abstract
Embodiments of the present disclosure describe a method of fabricating a thin-film composite membrane comprising immersing a porous support in an aqueous solution containing a diamine; contacting the immersed porous support with an organic solution containing a multifunctional acyl chloride for at least 5 minutes and at a temperature of at least 50° C. to form via interfacial polymerization a polyamide thin film on the porous support; and drying the thin-film composite membrane at about room temperature. Embodiments of the present disclosure further describe a method of separating fluids comprising contacting a defect-free polyamide-thin-film composite membrane with a fluid composition and capturing one or more chemical species from the fluid composition.
