Thin film nanocomposite (TFN) membranes were prepared by incorporating pristine (HNT) or modified (mHNT) halloysite nanotubes into the interfacially polymerized polyamide (PA) layer of the TFN for gas separation applications. N2, CH4 and CO2 permeances of TFN membranes were increased by the addition of both HNTs and mHNTs. However, gas permeance of mHNT-TFN membranes was always lower than that of the HNT-TFN ones, while the mHNT-TFN membranes were more CO2 selective. The CO2/CH4 and CO2/N2 selectivities of TFN membranes were decreased by the addition of HNTs or mHNTs up to 0.03 %w/v, in comparison with the TFC membrane. However, the TFN membrane containing 0.05 %w/v of mHNTs showed...
