The growing needs to improve gas separation performance of polymer membranes have led to the development of thin film composite (TFC) membranes by interfacial polymerization (IP). TFCs are composed of a thin selective polyamide layer prepared by IP method coated on a porous substrate. Recently, thin film nanocomposite (TFN) membranes; a combination of IP-TFC and inorganic nanoparticles, have opened a way for exciting new research in the gas separation area. Tubular nanoparticles such as halloysite nanotubes (HNTs) have great potential for use in gas separation processes due to enhancing gas permeability of membranes. In this work, TFN membranes embedded with different loadings of pristine or modified HNTs (mHNT) were fabricated by interfacial polymerization method on a polysulfone substrate for CO2 separation applications...
